I plan on buying maracas in Mexico, but yes, I want tumblers. That , plus other OOT bag items, centerpieces, possibly fake flowers, etc makes me nervous how many suitcases I will need. Plus I feel like I will want to bring so many clothes because I want to look cute during the week and won't be able to decide what to bring. I was thinking of maybe getting a credit card for whatever airlines I take, and that would allow me to check something for free.
