Reading these posts gave me an "Ah Ha" moment. If I was checking in at the airport I would be tipping both the hotel Bellman and the Skycaps. Guess airport hotel check-in should be no different. However, I would not normally tip the person giving me my boarding pass. I'll be keeping it in mind when we travel to the world in Dec.
This is the problem--it's so confusing because no one ever tips the airline employees at the airport check-in who give you boarding passes and take your luggage, right? How did the resort airline check-in people suddenly become skycaps?
Skycaps at the airport now generally have a straight per bag handling fee. Those at the Disney resorts do not. Furthermore, Disney covers tips through the Magical Express system (you don't tip the guys who leave your bags in your room for instance) so why is leaving and going home any different?
Also, being asked point blank for a tip is not appropriate in any circumstances. If there is a fee involved, then that should be specified, but I still do not think that someone putting a tag on my bags deserves cash for that.
