How much would you actually tip housekeeping? $3 - $5 per day too little/too much, it's just a different world over here LOL we really only tip in Aust for good service, I worked in a casino and we were not allowed to accept tips or we were automatically dismissed.
I really don't know.
It's usually a pleasant surprise for the housekeeper.
I do know that what you tip at the All Stars might be less than if you were staying at the Grand Floridian.
I would think $2-$3 would be sufficient. But since you leave it ahead of time, it is hard to say b/c you don't exactly know how great of a job they will do.
Casinos on cruise lines can accept tips, I do not know about land casinos. I think I went to one once in Kansas City and I think they could accept tips.
Very different system in the US, of course. Employers don't like to pay the employees all that much.
I do avoid the change cups on the counter service counters though. That really irritates me for some reason. Not much of that at WDW.
But if you come across change cups off site, it is not customary to tip in those and is considered a mild nuisance by many Americans.
However--again. "It might be their only source of income and they don't make very much..." Well, that is their choice to work there, but it doesn't make it okay to request tips in a non-tipped position. (As it doesn't make it okay to increase the standard just b/c they want to make more money.)
