I've never done it at Disney, but I did exclusively do cloth diapers with my son. I never had too much trouble. I think that it depends on your personality, the people around you and what sort of washing machine access you will have at your accomodations. I think that I would have been able to easily deal with it back when my son was a baby. But by the time his sister came along (six years later), circumstances had changed in my life and there were several times that I switched to disposable diapers for certain events. You just have to decide how much the convenience factor will mean to you, how much the cost of the disposables matters to your budget (probably not much if you'll be laundering at a coin laundry), and go with your gut. I do think that cloth is far superior, but it is certainly not the only correct decision.
