You are welcome to rent a car but probably don't need one. Austin Airport is about 15 minutes from downtown (where both of our wedding hotels are located) and Uber and Lyft are easy and accessible in the city. There are plenty of food and drink options downtown as well! We will have free transportation to and from the wedding itself and our Friday night welcome party is a short 5 minute ride or 10-15 minute walk from the Line Hotel.
Although we love your little ones, the wedding and reception are an adult only affair (except wedding party/family).
