Although they're no longer the majority, a number of Caribbean all-inclusives remain couples-only or adults-only properties, which many consider a "must" for a romantic couples getaway.

Among the all-inclusive brand-name chains, the couples-only Sandals resorts are especially renowned for their exotic, romantic locations. The Sandals Royal Bahamian in the Bahamas, for example, features a private offshore island, villa suites at the exclusive Royal Village, an excellent spa, and white-glove service at a choice of eight gourmet restaurants.

The romantic appeal of all-inclusives has long attracted newlyweds, and paying one price for your honeymoon eliminates a major source of stress for young couples.

Most all-inclusives welcome honeymooners with at least a few extras like champagne in their room upon arrival, and also offer destination-wedding services for those who want to get married during their stay. The complimentary wedding package at Couples resorts, for example, includes a personal wedding coordinator, nondenominational ceremony, wedding cake, flowers, and couples massage.For an additional $399, couples can get a private wedding reception for up to 10 guests, a private candlelit dinner, and other amenities.
