You can find some place to stay at every price point on Barbados, although there are quite a few more places at the top end than at the budget end.
Camping is generally not allowed on any public lands.
Most hotels add a 7.5% government tax plus a 10% service charge, and many have a minimum high-season stay. As elsewhere in the Caribbean, rates decline by as much as 40% outside of high season.
High Season Prices
In high season (December to April), expect to spend at least US$150 per night for a nice midrange double on, or more likely near, a beach. But shop around online as there are deals to be had.
