In Central America you could consider Belize. It’s small, but it’s got islands and beaches (not everywhere though) and forests and other cultural sights, and English is more or less the official language. It’s not as well organized as Costa Rica, but it’s not bad and it feels safe. The other to consider there is Panama, which obviously has a lot in common with Costa Rica. It has far fewer adventure activities and the good beaches are spaced out a bit, but still it’s a relatively rich country with tens of thousands of Americans and Canadians living there as well as visiting, so they have a good tourist infrastructure and it’s safe.
Located off the coast of East Africa, the Seychelles—an archipelago consisting of 115 islands—is about as close to paradise as you can get. Crystal clear water, lush jungles, and powder-fine sand make it the ultimate early winter escape, particularly for romantic getaways. Book one of the 30 breathtaking pool villas at Six Senses Zil Pasyon, which is among the region's top luxury resorts. The hotel is situated on a private island that offers prime territory for snorkeling, sailing, kayaking, and hiking—plus, the spa has scenic pavilion-style treatment rooms that are worth the trip alone. Health conscious guests will be particularly impressed by the property's new "Eat with Six Senses" program, which is intended to make travelers leave vacation without the guilt that comes with overindulging. There are four tailor-made treatment plans that focus on sleep, detoxing, fitness, and more, depending on the issues you prefer to address.
