Did you like St. John's gracie. We visited there in conjunction with St. Thomas and within 2 days we were bored out of our skulls.
Most of the island is a state park so they can't build and every thing seem to go slower than even the speed of the caribbean, which is slower to begin with. I will admit though, we're not into hiking.
I thought it was beautiful but 2 days was definitely enough.
I have not been to St. Johns. I was in St. Thomas, and I was in Puerto Rico (just for a day. I would like to go back to Puerto Rico, because we really didn't get to do anything. St. Thomas was beautiful!
