Can anybody provide some general tipping help and guidelines while staying at a DVC resort? Do you leave a tip for housekeeping-if so, only for a 4 day or longer stay? How much is enough? Also-how about for luggage? Do you tip when bags are stored until the room is ready? And then tip again when they bring them up to the room? What is a fair tip for this-ie is it per bag? Do most people have someone bring their bags up or are there a lot of 'do-it-yourselfers? It seems there are a lot of opportunities to tip-even on the Mears ride over-and advice for when, where and how much would be appreciated!
