St Martin was not vey impressive. Marigot while cute, was overrun with people & dirty. Good jewelry prices on Dutch side, Try Zhaveri. Next time we will just go to a beach & make the best of it. Snorkeling on St John on the St Thomas day was awesome. We were lucky to have calm seas & good weather -- Trunk Bay our US National park is not to be missed! The underground marked trail is lots of fun & the snorkeling is easy with great rewards.
