Well, considering you're paying for a room with daily service, it should be included in the rate. Especially if they don't get tipped much anyway. That said, if they do a nice job for the course of my stay I'll leave $5-$10 for the trip (not per night).

A bad experience regarding tipping in my experience was at Paris, where we had a deal that was something like 3 nights + trip to top of Eiffel Tower + buffet + match play + tip included for bellhop. We sign in with specific deal downstairs and told it is taken care of re: bellhop. Bellhop comes to room, insists he's never heard of the promotion and he doesn't get anything, and doesn't leave until he receives a tip. Start of one of the worst experiences we've had at a hotel (felt like we were treated like true Americans in Paris the whole time).
