And a very few hotels have special lounges for guests who arrive early before their room is ready or who have a late flight so that they have some place to spend time from checkout until time to go to the airport. The general scheme is that elite status isn't required and the lounge offers minimal F&B, something like coffee/tea/water, perhaps with a pastry or two at breakfast time. Unfortunately I can't immediately think of a Starriott that has one of these "lounges."
