You will experience things the winter tourist never sees. The restaurants coordinate and close like building blocks one at a time so there are always plenty of good ones open The trees and flowers are budding, soon to be in full bloom. We have had plenty of good Spring rain, an hour in the morning, enough to cleanse the air and water the plants. See a Flamboyan Tree as it was meant to be. Alas, the winter tourists never see this.
Prices are by and large lower.
Many homes offer summer prices. This affords people the ability to have a pool or to be on the beach. The hotels and guesthouses have special deals, many with cars. Call them to make sure you know the prices at this time of year. The Vieques Historical Trust has had a facelift.
