We have just returned from a very short 2 day trip to St. Maarten and had a wonderful time. We rented a car from Leisure Car Rental (see that review on the travel forum) and that was an extremely pleasant experience.
We stayed at Sonesta Great Bay Beach Resort where we had stayed on our honeymoon 12 years ago. They have done a good deal of renovations since then and the hotel looks very nice. The room was big and quite comfortable. All hotel staff were friendly and helpful. Buffet breakfast was nice and the guavaberry coladas are the best!
We had dinner one night at Jimbo's Rock and Blues Cafe. Very tasty mexican food and margaritas. Beware of the fish bowl margarita, however. They are huge!!
Our second day was spent shopping in Phillipsburg - lots to buy!
The trip was much too short but we had a great time.
