Flight
AUS is the airport guests should fly into. This weekend is also Austin City Limits (a big music festival), so we recommend booking early to avoid high flight costs. The San Antonio airport (SAT) is a 2nd option, which is just under 1.5 hours from Austin.
Hotel
We recommend staying AC Austin Hotel by Marriot Austin Hill Country (we do not have a hotel block, as the nightly rate was more than listed price on their website). Please book ASAP to avoid escalating fees. The shuttle for the wedding will depart from the hotel at 4pm on Friday, so plan accordingly! Guests are asked to arrive by 4:30pm. Lyft/Uber will be available if you cannot make the shuttle, and parking is available at the venue overnight (you will need to pick up your car the following morning by 10 a.m.). Airbnb and VRBO also have a variety of lodging options for groups to consider.
