For the events we will be using the shuttles from the inn to move people around where they need to be. For all other times, you can rent a golf cart from Dyl's. (https://www.dylscarts.com/)
For those staying on island, you may want to consider getting food from a grocery store on the main land before leaving for the island. Once you're on Chebeague there is a convenience store called Doughty's Island Market, and 2 restaurants (the one at the Inn, and Slow Bell Cafe).
For the wedding day, please wear formal wedding attire (Suits &ties for the men, cocktail dresses and gowns for the ladies). For the welcome drinks on Friday, the attire is semi-formal/garden attire (For women, elevated but relaxed. Dresses, jumpsuits, and a blouse paired with pants or a skirt are all appropriate. Consider a block heel given the grass. Florals are encouraged. For men, button-down shirts and slacks. Bonus points for blazers.)
