If the hotel has pool, workout room, tennis court, etc. then I always ask during checkin if all of these facilities are open and available during my stay. If any are not, then I expect some type of compensation directly from the hotel, which could be in the form of a discount, dinner or breakfast comp, etc. The fact is that I'm paying for these facilities in my room rate, and if the pool is closed, then I'm not getting what I'm paying for, so I must have some compensation. Using another hotels pool or workout room doesn't work for me. If talking directly with the hotel doesn't work (which it usually does for me), then I have to get on the phone or send off an email asking why that hotel is charging me for something which is not available.
