Yes, the dress code is beach formal.
Yes, we recommend that all of our guests rent a car, or at least coordinate with other guests to have a car at your disposal. The island is not large, but a car is a necessity to be able to enjoy it fully. We would only recommend going without a rental car if you did not intend on leaving your resort. Turo (the phone app) is a great option - they will drop off and pick up your rental car. There are several big-brand rental car companies at the airport, but please keep in mind that depending on the day/time of your arrival, these can get quite busy. (Pro tip: If the rental car line is long at the airport, you can sign up to be a preferred member while you're waiting and skip the extra long line!)
Yes, and the 1 Hotel is valet only. We highly encourage our guests to pre-schedule an Uber to and from the venue if they are staying far away, though!
