Villas come in a variety of sizes, from cozy one-bedroom cottages to sprawling compounds with 10-plus bedrooms and guesthouses. Some are staffed; others embrace the do-it-yourself spirit. Available amenities can be as basic as air conditioning (no, it's not a given) or as over-the-top as private tennis courts or your own helipad. At a villa you can customize your accommodations, meals and activities to your taste on your schedule. You'll also get a glimpse at island life from the perspective of the residents (especially if your villa is staffed), along with the freedom to do what you want, when you want — and all in the privacy of your home away from home. See our list of booking tips to ensure you get the villa vacation you want at the price you can afford.
