We will be cruising on Allure of the Seas on Mar. 4-11 and it will be our first cruise. I have read many of the posts and they have been very helpful but I still have some questions I hope can be answered. First, We have My Time Dining and have been assigned the American Icon Rest., can we go to the other dining rooms and what time would we need to go to eliminate waiting long. Is the menu the same at the different main dining rooms. Secondly we enjoy our coffee in the morning and we have a CP balcony. We were wondering about the complementary breakfast and is it on the room service menu or is there a other way to order. Finally we have paid our gratuity up front when we paid for the cruise. Who and what does that initial gratuity cover? Are the room staff included in that gratuity, if not we want to make sure they get their tip. We are not getting the drink package so we know the gratuity is included when we buy the drinks. Thanks everyone for the answers we are looking forward to the warm temps. and relaxation.
