Two weeks ago we went to Guest Services to borrow a stroller. No fee, we could take it off the ship, and it did recline so DD could nap while we walked the streets of St. Martin. I believe it was a Grayco, with a basket underneath. It folded so we could store it in our closet ( Not an umberella stroller, though). The wheels moved like any other stroller. There are other strollers at Castaway Cay with special large wheels. I'm not sure about any fee.
