Yes, in most cases you get far more than a name and a price. Along with the room and rate details, the hotel booking API can supply photos, a written description of the property, the facility list, the star rating, the full address and the map location, so your website can show a complete hotel page rather than a bare line of text.
In practice this information usually arrives separately from the live prices. The descriptions, pictures and facilities are fairly static, so they are collected once and kept ready to display, while availability and rates are fetched fresh every time your customer searches. That is why a hotel page can load quickly with all the detail on it, and the price appears as a live result.
Be aware that the richness of this content depends entirely on the supplier and on the property itself. Large hotels and chain properties normally have plenty of good pictures and a long description, while small guesthouses and apartments sometimes have only a short write up and a handful of images. Descriptions are usually in English, and translations into other languages are not guaranteed for every property. Some suppliers also set rules about how their photos may be used or displayed. If you have your own direct contracts, you can load your own pictures and wording for those hotels so they look exactly as you want.
Before you go live, it is worth asking us to show you sample hotel pages for the destinations you sell most, so you can judge whether the content quality is good enough for your customers.
