My husband and I went on our Honeymoon in Feb this year. We posted everything on our Amex and the total was about $2600. Please don't laugh.
We spent about 1500 in Cozumel on jewelry. We also spent about $500 at the art auctions and the rest on souveniers, gratuities, casino, etc. Remember your grat is $10 per person, per day, plus any additional that you decide to give to diferent people. The last night at dinner you are reminded that your maitre d is not included in the $10 per day so people usually bring cash in an envelope to dinner that night and give it to him.
