HolidayHero vs GreatStay

GreatStay, from Dutch company Great Stay App, builds accommodations their own branded guest app, QR web app or website, filled with the property's content and managed through a CMS, delivered with a hands-on strategy, design and implementation process. HolidayHero is a whole-stay guest experience platform: one system that runs everything between booking and review per reservation, from online check-in and AI-powered messaging to upsells, smart-home access and guest analytics.

Where GreatStay is strong

Credit where it is due: GreatStay ships a genuinely own-branded native app (not a white-label shell), backs it with an agency-style guided process, and is deeply plugged into the Dutch recreation ecosystem, with partners from Stratech, Tommy Booking Support and Booking Experts to Mews, RoomRaccoon and Camping.care, plus a long list of lock, POS, restaurant and ticketing integrations. Over 750 accommodations use it, and the separate Great Review product adds smart review collection with AI-assisted responses. If what you want is a polished branded content app for your park, they know this niche well.

Why HolidayHero

The difference is what happens after the app is built. A GreatStay app is primarily a content and communication tool: pages, practical information, push messages, an order module. HolidayHero is built to run the stay itself, per guest and per reservation.

That starts before arrival. HolidayHero handles online check-in with configurable fields, ID and passport capture, and automatic guest registration filing with authorities (live for Spain's SES Hospedajes). Messaging is two-way and personal: one inbox across email, WhatsApp and SMS, with Booking.com and Airbnb threads and PMS guest messages synced in, scheduled templates gated by conditional rules, and an AI concierge that answers and actions guest questions autonomously with human guardrails. GreatStay's documented communication tools are one-to-many push messages and pop-ups; for a shared inbox it partners with third-party tools rather than shipping one.

On revenue, both offer in-app ordering. HolidayHero goes further down the chain: charges can post to the folio via supported PMS, local experience inquiries route directly to the supplier who fulfils them through their own portal, and commission splits are calculated automatically. Guest data then becomes an asset: guest-app analytics, sentiment detection and a composite 0-100 engagement score let you catch an unhappy guest before checkout, and a workflow builder automates the follow-up. GreatStay documents app usage statistics; in-stay intelligence of this kind is not publicly documented.

Access control is another scope difference. GreatStay integrates with a solid set of lock partners. HolidayHero covers locks (Goki, Bold) plus a full smart-home layer: thermostats, sensors, energy management and more, gated per reservation stage.

Commercially, the two models differ. GreatStay is demo-gated with no published pricing for its apps and web apps; HolidayHero publishes pricing from €6.50 per unit per month, lets you start on a free trial self-serve, and takes no commission on your own guests. For teams with their own product ambitions, HolidayHero also offers an integration API and a headless guest app, so the guest experience can live inside your own app or site. And as an EU-native platform, GDPR compliance, EU data residency and first-party data ownership with export are stated commitments, not assumptions.

Capability by capability

Both do branded guest apps well: custom look and feel, modular sections, guidebook-style practical information and an activity calendar are solid on both sides, and GreatStay's own native app is a real strength for long-stay parks. GreatStay's onboarding process (strategy, content and design, implementation) is well defined, as is HolidayHero's guided setup.

From there the grid tilts by scope. Arrival: both document online check-in; HolidayHero adds ID verification natively (GreatStay lists a Scanfie integration) and authority registration filing. Messaging and AI: HolidayHero's unified inbox, WhatsApp channel, OTA and PMS message sync and autonomous AI concierge have no publicly documented GreatStay equivalent. Revenue: GreatStay's order module and ticket-shop integrations cover upsells and area tips; folio posting, supplier routing and automatic splits are not publicly documented. Operations: app statistics on the GreatStay side versus guest analytics, sentiment, engagement scoring and workflows on HolidayHero's. Reviews: GreatStay covers this with in-app surveys plus the separately priced Great Review product; HolidayHero includes in-stay surveys and review generation in the platform. Trust rows (GDPR, data ownership, PCI) are stated by HolidayHero and not publicly documented by GreatStay.

Which fits you

If all you need is a branded content app for your holiday park, built for you by a Dutch team that knows the recreation sector and its booking systems, GreatStay is a fine pick. If you want the app to be the front end of something bigger, a platform that checks guests in, messages them personally in their language, sells and settles upsells, watches sentiment and automates the work in between, HolidayHero is built for exactly that, at published per-unit pricing you can start on today.
