We live in Georgetown, which is 25 min north of downtown. Our apartment name is Rise 120 and 3 minutes from the Round rock Outlets, 15-20 minutes from the Domain. Lake Travis is 40 minutes west of us and where the boat will be taking off.
Austin is a very laid back city and almost everywhere you go there’s someone in a T-shirt. Some upscale restaurants have dress codes but almost no other places do. It’ll be warm so dress to your comfort level!
The lake is nice and cool, if you have water shoes I would recommend them but not necessary with the boat. There is no glass allowed so bring only cans, all food is ok. Definitely try to stay cool and lots of sunscreen!
