Planning winter vacay for Feb. 2015 already. Spouse has chosen MVC in St. Kitts. Bringing children ages 6 and 8. Do we need a car? Any tips on how/where/if to buy groceries for the villa and how to get them back to the resort without a car? Taxi? Any shops within walking distance of the resort? Not sure that we are adventurous enough to drive on the left side of the road! Do we need to exchange money, or do the shops take USD?
