Choosing the right upselling software is crucial for your hotel’s revenue growth and guest satisfaction. CityKey aims to enhance guest experiences through experiential partnerships and local integrations but has no recent reviews or significant user feedback to confirm its effectiveness. Meanwhile, Oaky by Plusgrade has built a clear reputation, with over 440 recent reviews and a nearly perfect 4.84 out of 5 rating, making it the more proven choice for hotels seeking to maximize ancillary revenue.
Both products seek to increase your hotel’s revenue through upselling, but their approaches differ. CityKey focuses on local experiences and personalized guest engagement, whereas Oaky emphasizes targeted, automated upselling across the entire guest journey. Do you want a platform centered on local perks or one that drives revenue via data-driven upselling?
CityKey offers a guest experience management platform that leverages AI to analyze reviews and recommend improvements, with a focus on local experiences to boost room sales. However, it has no verified integration partners or detailed feature set, and its review count is zero, which raises questions about its current utility and user adoption.
In contrast, Oaky is a comprehensive upselling tool with 54 verified integrations, a broad feature set, and a proven track record of increasing revenue. Its reviews highlight high satisfaction with automation, personalization, and ease of use, supported by recent feedback from over 440 hotels. Are you looking for a platform with proven revenue results or one still emerging in the market?
If your hotel needs a flexible, feature-rich upselling platform that can be integrated into your existing tech stack and deliver measurable revenue growth, go with Oaky. Its extensive feature set (12 exclusive features like guest segmentation, multi-channel delivery, and offer experimentation) makes it ideal for mid-sized to large hotels focused on data-driven upselling.
If your hotel prioritizes enhancing guest experiences through local partnerships and experiential offerings without needing advanced upselling capabilities, CityKey could appeal. However, given its lack of recent reviews or verified integrations, Oaky’s proven success in driving incremental revenue makes it the safer, more reliable choice.
Oaky’s user interface is highly rated, with a 4.84 out of 5 ease-of-use score and positive reviews highlighting how intuitive and quick to manage it is. Its onboarding process also earns a 4.74/5 rating, and users frequently comment on how rapidly they see results with minimal training needed.
CityKey has no available user ratings or recent reviews, making it impossible to assess its ease of use. Its lack of user feedback suggests uncertainty about its onboarding experience and staff adoption. Edge: Oaky.
Oaky offers 12 unique features, including guest segmentation, A/B testing, multi-channel delivery, dynamic pricing, and offer orchestration—capabilities that enable tailored, automated upselling campaigns. CityKey, with no verified features, appears to have a narrower scope, focusing on local experience partnerships rather than direct revenue-driving tools.
The depth and variety of Oaky’s features allow hotels to customize strategies, increasing upsell conversion and guest satisfaction. Given the comprehensive feature set and recent reviews, Oaky has a clear advantage. Edge: Oaky.
Oaky’s recent reviews consistently praise its customer support, with ratings of 4.87/5 and comments emphasizing quick, knowledgeable assistance. Hotels mention how dedicated teams help with onboarding, troubleshooting, and optimizing campaigns, resulting in high satisfaction.
CityKey has no recent reviews or support ratings, leaving its support quality uncertain. Without verified feedback, Oaky’s proven support reliability makes it the better choice for hotels seeking dependable assistance. Edge: Oaky.
Oaky boasts 54 verified integrations with major PMS, channel managers, and hotel tech solutions, enabling seamless data exchange and operational efficiency. Shared integrations are nonexistent, but Oaky’s extensive partner list demonstrates its ability to fit into diverse hotel tech stacks.
CityKey has no verified integration partners, which limits its potential to work smoothly with your existing systems. For hotels prioritizing a plug-and-play solution with robust connectivity, Oaky’s integration strength is compelling. Edge: Oaky.
Oaky’s recent review count (443) and 4.84/5 rating reflect strong, current user satisfaction across various hotel segments—from independent boutique hotels to large chains. Hotels consistently praise its effectiveness in increasing revenue, ease of use, and support.
CityKey has no recent reviews, so there’s no data to suggest how hoteliers perceive it today. With proven ratings and recent feedback, Oaky clearly leads in hotel satisfaction. Edge: Oaky.
CityKey’s pricing details are unavailable, and it offers no free trial or transparent fee structure, which may complicate budgeting decisions. Oaky charges a base fee of $300 per month, with no implementation or setup costs, and no free tier.
Given Oaky’s transparent pricing and proven ROI, it’s easier to evaluate the financial value, especially since many hotels see revenue uplifts exceeding the platform’s subscription cost. Edge: Oaky.
Not ideal if your hotel needs advanced upselling capabilities, automation, or proven revenue uplift features.
Not ideal if your hotel relies solely on local experience marketing or has very limited upselling needs.
Oaky stands out as the more verified, comprehensive upselling solution, with a proven track record, extensive features, and high user ratings. CityKey’s focus on local experiences may appeal to niche hotels but lacks recent validation and detailed capabilities, making it a risky choice for revenue-focused hotels.
Choose Oaky if your goal is to increase revenue, streamline guest communication, and rely on a platform trusted by hundreds of hotels worldwide. CityKey might suit hotels that want to emphasize local partnerships above direct revenue impact, but it remains unproven at scale.
In summary, for hotels serious about upselling and revenue growth, Oaky offers a clear, evidence-backed path. Its recent reviews and high satisfaction scores confirm it as the stronger, more reliable investment for your hotel’s future.

| Criteria Group | Weight | What It Measures |
|---|---|---|
| Customer Ratings & Reviews |
|
How highly do users recommend this product? Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories ▾ The most heavily weighted factor. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias. |
| Partner Ecosystem |
|
How highly do tech partners recommend this company? Partner Recommendations, Integration Quantity, Integration Quality ▾ Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack. |
| Customer Centricity |
|
How customer-centric is this organization? Certified Support, Review Consistency, Profile Completeness ▾ Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features. |
| Reach, Staying Power & Resources |
|
How extensive is this company's reach and resourcing? Geographic Reach, Staying Power, Company Resources, Trending Score ▾ Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity. |
