With fall around the corner and kids heading back to school, it’s an ideal time for the grownups to get away, play and save at St. Thomas’ Bolongo Bay Beach Resort.

The Caribbean beach resort is offering two adults-only travel deals available on any stays of three nights or more from September 1 through October 31, 2011, including Labor Day weekend. With both offers, four friends can stay for less than $100 per person, per day.

Back by popular demand, Bolongo Bay’s Adults Stay Free offer includes a 20% discount on hotel rooms, plus the third and fourth adult (over 18 years of age) in a room stay free with two paying adults (on the room-only plan). With discounted daily rates beginning at $205.60 for an Oceanview Room, four friends can stay for a little more than $50 per person, per day.

For friends who are close but don’t want to room close together, Bolongo Bay is offering savings when booking two rooms. Friends can spread out and save 20% on the first room and 50% off the second room. If a group of four splits the savings, it’s $83.53 per person, per day for an Oceanview Room. Both offers are available on the resort’s Oceanview rooms and Beachfront rooms, which are steps from the sand. All daily rates are subject to tax, service and energy surcharges. The offers are subject to availability.

Guests receive a discover scuba diving in-pool lesson and complimentary use of non-motorized water sports equipment including Hobie Cats, paddle boards, windsurfers, kayaks and snorkel gear. At night, Bolongo Bay is the place to be on St. Thomas with two oceanfront restaurants and live nightly entertainment at Iggies, one of the best beach bars in the Caribbean. With no passports required for US citizens to travel to the US Virgin Islands and many direct flights available, it’s easy to take an adult beach vacation to Bolongo Bay.
