I posted these in my planning thread but thought I'd post here too. I bought bubba kegs for our wedding party and parents. I then ordered waterproof vinyl letters from an Etsy shop to put on them. I did black kegs with black upper case letters for the guys and navy kegs with yellow lower case letters for the girls( our college football team colors). They were super easy to do and I love how they turned out. I will give them to them before we leave so I don't have to lug them all to Mexico. For our guests, I plan to do stadium cups with some sort of personalized waterproof label.
