The verdict in three sentences
For a group of 5 four-star hotels in Lisbon, a 5-language website with a booking engine connected to the PMS costs EUR 25,000 to 45,000 excluding VAT and ships in 12 weeks. The business case is the 17 % Booking commission: moving from 18 % to 35 % direct bookings shifts hundreds of thousands of euros of revenue to a far cheaper channel. The budget depends mostly on translation quality and engine integration, not on design.
Line-by-line costing
A hotel group site combines a group page, 5 property mini-sites and a single booking funnel. Here is the breakdown of a median EUR 36,000 project.
| Item | Scope | Cost (2026 estimate) |
|---|---|---|
| Concept and design | Group identity, per-hotel templates, mobile mockups | EUR 6,500 |
| Site development | 5 hotels, rooms, offers, dining, meetings | EUR 9,500 |
| Booking engine integration | Widget or API, rate parity, promo codes | EUR 6,000 |
| PMS and channel manager connection | Real-time availability, rates, sync | EUR 4,500 |
| Translation into 4 languages | 15,000 words per language, EUR 0.12 per word | EUR 7,200 |
| Multilingual SEO | Hreflang, URLs per language, Google profiles per hotel | EUR 1,500 |
| Photos and content | Selection, WebP optimisation, source copy | EUR 800 |
Portuguese is the source language, with English, Spanish, French and German depending on guest mix. At EUR 0.10 per word for reviewed human translation, the line drops to EUR 6,000; at EUR 0.14 with hospitality specialisation and SEO adaptation, it rises to EUR 8,400. Machine translation alone should be avoided on conversion pages.
The real cost of booking channels
Direct booking is not free: the engine, card fees and marketing all cost money. But the total stays far below online travel agencies.
| Channel | Cost per booking | Note |
|---|---|---|
| Booking.com | 17 % | Typical observed rate, higher in the Preferred programme |
| Expedia | 18 to 20 % | Depending on contract and visibility |
| Direct site, engine | 2 to 4 % | Engine subscription or commission |
| Direct site, card fees | 1.2 to 1.8 % | European and international cards |
| Direct site, marketing | 3 to 5 % | Google Hotel Ads, metasearch, email |
| Total direct channel | 6 to 10 % | That is 7 to 11 points saved |
Net savings are therefore around 9 points per booking moved to the website, provided you respect rate parity and offer a direct perk such as free breakfast or flexible cancellation.
What the specification must lock in
Three points prevent bad surprises. First, the engine must show real-time prices in all 5 languages and at least 3 currencies, euro, pound sterling and dollar. Second, the funnel must not exceed 3 steps on mobile, since over 60 % of hotel site visits come from smartphones. Third, conversion tracking must be set up per hotel and per language from launch, to steer towards the 35 % target.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Inês Carvalho, commercial director of a group of 5 hotels in Lisbon, Cascais and Sintra, generates EUR 10 million of online room revenue, 18 % of it direct. The new EUR 38,000 site lifts that share to 35 % within 18 months. The 17 points shifted represent EUR 1,700,000. Net savings of 9 points on that volume reach EUR 153,000 a year. After EUR 6,000 of annual maintenance, the site pays for itself in just over 3 months at cruising speed.
FAQ
What budget for a hotel group website in Lisbon in 2026?
Plan EUR 25,000 to 45,000 excluding VAT for 3 to 6 hotels in 5 languages with a booking engine and PMS connection. A single independent hotel starts around EUR 9,000.
How long does it take?
Twelve weeks is realistic: 3 of design, 5 of development, 2 of parallel translation and 2 of booking tests. The PMS connection is often the critical path.
Should we translate into 5 languages at launch?
Yes if international guests exceed 40 %, which is common in Lisbon. Start with rooms, offers and booking pages, about 60 % of the word count.
Can we show a lower price than Booking on our site?
Wide parity clauses are restricted across much of the EU, and the Digital Markets Act now bars Booking from imposing them on hotels. Many hotels still prefer a service perk, which is simpler to manage.
What direct booking rate is realistic?
A well-ranked four-star group reaches 30 to 40 % direct bookings. Moving from 18 % to 35 % in 18 months requires a direct marketing budget of 3 to 5 % of the related revenue.
