In Nuevo Vallarta, you can lounge on the golden-sand beaches of Banderas Bay… or take an ATV tour through the nearby Sierra Madre jungle. A local water park has great twisting slides and sea lion shows… or you could treat the kids to a memorable swim with dolphins. (It'll make for a great "What I did over summer holiday" report.)

Port of Spain, the capital of Trinidad and Tobago, has the tall buildings, neon lights and crowded streets of many cities, plus a multicultural Caribbean character and a home-grown calypso soundtrack. The best-known event is the flamboyant pre-Lenten Carnival. Among the city's other offerings are cricket and football matches, year-round festivals, a botanic garden, malls, an art and history museum and historic buildings. Entertainment options abound, but be cautious after dark.
