If you are putting a lot of $ worth of wedding stuff on your credit card (I earn miles) then I would suggest calling your credit card company and letting them know that you'll have a lot more charges than usual.
My credit card fraud prevention called me on Saturday while I was sitting in the chair getting my makeup done. It was no big deal, but it would have been nicer if I hadn't gotten the call.
Also, good luck to everyone! I was super stressed for several days before and the day of the wedding up until they opened the doors and I saw R standing at the end of the aisle waiting for me. After that, everything was perfect.
