We bought our tickets with Southwest yesterday too! Now we just need to wait for the special Food & Wine Festival Events to become available for booking and we will be all set!
Here's some pixie dust for you - It was defintely just luck that I heard the ding and did some rapid changes on our return flights - originally set for the 3rd- it was just too bad that I had to add an extra day and lucky that I could get the extra night at SSR.
