How much is it appropriate to tip in Palm Beach?

Question

I'm going to be traveling to Palm Beach in two weeks, and I wanted to make sure I don't offend anyone, specially people I may need to ask for favors later :)

From the van that'll transfer me to the hotel, to waiters and hotel staff; when and how much is it appropriate to tip?

A concrete example; how much should I tip the person that takes my bags from the check-in counter to my room?

Answer 1

For wait staff at restaurants: from 10%-20%, depending on quality of service. For the bell-hops (the person that takes your bags to your room): $2+ ($1/bag, with a $2 minimum).

Here is a good reference source.
