Which river are you floating? We are floating the comal.
Since it's your first time, here are a few tips I wish someone would have told me my first time! Bring a floating cooler, bring some cheap walmart throw away sunglasses that you won't be bummed to lose, and bring some water shoes. The bottom of the river has lots of rocks and will hurt your feet if you have to get out and walk, and it's slippery. I bring tennis shoes.
Lots of sunscreen, and PACE yourself on the drinking. Last year I went way too fast and got really sick at the end of the float! 95 degree heat, plus lots of beer in a short time span= no bueno for Natalie!
It's SO much fun though!!
