The Four Seasons Resort in Costa Rica is popular with businesses looking to combine team building with social responsibility. The five-star luxury resort works with a program called Growing Together to organize custom volunteer experiences based on your budget, experience and time. Groups help communities on Costa Rica's Papagayo peninsula; your team may be tapped to plant a garden, paint a school, or build a fence.
Cost: Rooms start at $395 a night; the hotel arranges the volunteer work for free, but you'll pay for costs such as transportation, which runs from $800 to $3,000 depending on group size and preferences.
