if fine dinning is important, it seems around September 1 is the date when restaurants take vacations

there still will be way too many options as we are on island for three weeks starting the second week of August and still don't fit in everywhere we would like to eat

restaurants are very good at responding to emails concerning their vacation dates so you won't be disappointed if you are surprised by a closure

most restaurants are not busy and have move time for service and reservations are not necessary but appreciated
