I am planning on using Tiffany as well and I am making my reservations today hopefully. Anyway, I'm confused about how to tip. I believe the tip should be 20%, so I will have them pick me up at the airport and take me to the Poly, then on the 5th day they will pick me up a the Poly and take me to the Portofino Bay Hotel and then a few days later take us from the PBH back to the airport. I was given one price for the whole thing, so how do I tip. Can I pre-tip for the whole thing, or should I have them brake it down so that I can tip each driver for each leg? I'm confused.
