Bear in mind all of this is in Mexico, in case that is relevant.
How much do I tip the DJ?
Do I tip the Officiant considering I'm paying the officiant?
Do I tip the mariachi band at cocktail hour? How much?
Do I tip the servers at dinner? Individually or like, all of it to one of them? How much?
Am I missing anyone?
ETA: I need to figure out how much cash to bring on the trip.
