Hotel
The Hampton Inn and Suites has easy access to the 101, and is 3 miles away from the wedding venue. Perfect for carpooling or uber access. You are close to Buellton, and within a 10 minute drive of Solvang and Wine Country. You can call the hotel directly and ask about the Carson/Wexler Block, or book through the website using the group code 'CWW'.

Hotel
This hotel has a larger feel to it, and was not built as recently as the Hampton Inn & Suites. However, there are plenty of rooms and it is just down the road from the Hampton Inn, so it has the same easy access to the freeway and Rancho San Antonio.
Flight
If you are flying in for the weekend, Santa Barbara Municipal Airport (SBA) is going to be the closest airport to access Santa Barbara and Buellton. There are car rentals attached to SBA, so it is very easy to breeze in and go. However, service to this small airport is somewhat limited and pricey. If you want to have less flying time, more driving time, but a cheaper airfare, then this is not the airport for you, and you should check out Bob Hope Airport in Burbank, or LAX.
