Ok, I never thought about tipping in the rainforest. I suppose that someone has to clean the room, but other than refreshing the towels, it is just the evening cleaning.....maybe I'm just justifying. Surial, they are cleaning up after YOU, same as cabin steward. So, I've considered a tip appropriate there. Wow...I really never thought about tips in rainforest......oooops...?
The other services, I've always figured that a 15% tip was expected, more for super service. Tips are usually just put on the charge ticket and go to your KTTW card, but I'm sure they'd accept cash (hee hee).
