ASAP!!! Please book your lodging and travel as soon as you can. This is a small island that fills up fast! Airline tickets will be the most affordable between mid-January and the end of March. Please note, the summer schedule ferry tickets will not go on sale until March 2019.
Although this is an island, we would like to keep this day special. We recommend formal attire. But we want you to feel comfortable too, so plan on casual shoes - women think cobblestones and grass - and men if that top button is too tight, loosen up! You are on a mini holiday after all!
The Nantucket Book Festival is this weekend as well. You may want to make dinner reservations for Friday night or other activities in advance of arriving on the island.
