We are hoping to book for 09/2017, and I have so many questions. -Do any of the rooms have bathtubs, or just showers (not a jacuzzi room...out of my budget!)? -Anyone with celiac disease have info on gluten free food options/availability? -Are there decent chances of asking for and being given an upgraded room at check in? -What's your favorite type of room? -I read that clothing is required in restaurants. For the more casual restaurants, how sexy casual can you get? We honestly want to pack as few clothes as possible, but I'd like to participate in the nightly themes, so I don't want to have to take a lot of clothes just to wear to eat. -How are the massage services? -We have never been to Mexico...do we need to avoid the drinking water?
