To offer any concrete suggestions, you'd have to provide many more details (geographical & network topology, networking gear in place already, types of cabling, services to be offered e.g. HSIA / VoIP / VoD etc).
Will the hotel use the networking infrastructure to only provide high-speed Internet (HSIA) to guests, or will it also use it e.g. to connect its own equipment e.g. POS, or provide VoIP or video-on-demand to guestrooms etc ?
Do you want to achieve redundancy in terms of WAN connections i.e. to utilize the hotel's 1x fiber & 2x ADSL WAN lines, and if one of them should go down then the guests' Internet traffic would be re-routed via the WAN connections that remain up ?
Anyway, my suggestion would be to hire a consultant who has done this before.
