"Near Hospitality House" includes buildings 11-14 and 23-26 which are all "near" the main pool, Olivia's and Front Desk.
IMO, also "close" to the Hospitality House includes buildings 62-64, 15-18 and 27-29. (62-64 and 15-16 are as close or closer than 23-26.) I'd reserve the "Hospitality House" guarantee, if available, or request the other options if it's not available. Requests won't be guaranteed though.
