Good Question.
I'm working on the tipping as well.
We will tip:
Carolyn Allen's
DJ Silva
Limo Driver
Rev. Jack
We will probably send Karen something - I have heard that they can't accept cash, but what about if we give her an AMEX gift card?
We probably won't tip the hairdresser - she is her own business.
I can't remember if i'm forgetting anyone else..
