We've seen Buffett more times than I can count. Let's see - wear your most outrageous Caribbean clothing! Grass skirt, leis, tropical shirt, coconut bra, funky hats, etc. - don't worry you'll fit right in. It's the people that DON'T dress up that are looked at funny. Buffett concerts are a big party. Join in the fun! Bring a couple inflatable beach balls to hit around (there'll be a lot of other ones floating around), drink lots of margaritas, make some new friends, and join in the singing!
Have a great time, and let us know what you thought of your first Buffett concert when you get back - we're going to the one in Cincinnati in August and are only 7 rows from the stage!
