Planning on arriving Oct 4 around 3pm and going directly to Nevis where we will stay until the 10th. Will stay at Park Hyatt for 3 days until flying back on 13th. Would the easiest option be to rent a car at St. Kitts Airport and keep for the entire stay? If so, does the car ferry only run at certain times (would we possibly miss it)? Or should we do a rental in Nevis and use taxi and the airport shuttle in St. Kitts. Thanks!
