Dayclubs and nightclubs are managed by completely different entities than the hotel/casino resort properties on which they reside. As such, dayclubs and nightclubs DO NOT give discounts to standard hotel guests for booking table service.
As a courtesy, dayclubs and nightclubs usually will allow 1-2 extra guests above the standard guest limit for each table reservation option if one or more in the party is a hotel guest and shows proof; they will also allow free general admission into the club with a hotel room key if you arrive early enough and they are not slammed. However, they do not offer discounted or comped table service for hotel guests, unless you are a casino whale gambling six figures at their establishment every visit.
