I just want to reassure everyone that I am an excellent tipper (always quite a bit over 20%), and have already included tips in my vacation budget. In my OP, I was wondering about "surprises" that might come up, that I hadn't anticipated. After reading about the giant sundaes (and being reminded about alcohol), it looks like I want to add a bit more fun money than I had anticipated. Everyone has been very helpful! I really appreciate everything!!!
