Yikes, I would be extremely nervous waiting till you get there. You may not be able to find what you are looking for, and I can almost guarantee you the prices will not be the best. Also,I don't know about you, but the last thing I would want to do when I step off the plane in Mexico is go searching for OOT bag items. I'll be drinkin and partying instead LOL! I guess, just try and pack light and squeeze it all in. ME, My FI, and mom are taking huge bags so we can fit everything
