This CheapCaribbean.com deal knocks an additional $120 off already reduced prices and saves more than $300 on the regular cost of purchasing airfare and hotel stay separately.

The offer is available for select departures April 7 - May 13. Additional nights also can be added at reduced rates.

Note: No passport is required to visit the U.S. Virgin Islands. When booking online, pricing initially will appear as $639, but the final price of $689 reflects mandatory hotel fees.
