If you're staying in Seaside, all of the events are in walking distance. If you're staying outside of Seaside you can park anywhere on 30A (main road Seaside is on), in the center of the town, use the valet, or use the parking lot in between Seaside and Watercolor.
Cocktail for the wedding and casual for the rehearsal dinner. Ladies, you will be walking in sand and grass so you may want to leave the stilettos at home.
Seaside is beautiful this time of year. Expect sunny days and cooler evenings. It can get windy so a light jacket or sweater is suggested at night. Be sure to check the weather online leading up to the wedding!
