We spent 4 nights in Orient Beach last month and did not rent a car. Of course it was more expensive to rely on taxis but it was worth it for us since we like to have drinks with dinner but will not drink and drive.

Two nights we dined in Orient Village and 2 nights we took a taxi over to Grand Case. We used a taxi twice during day times hours to go to Marigot. In the past I have rented a car for a portion of the trip to explore during the day but I know I will not use it in the evening, so either way I am spending money on taxis.
