I wasn't sure if we would get to go here due to Tropical Storm/Hurricane Tomas but the tenders were running very smoothly with no wait. We didn't book with carnival, instead I decided to book through Moby Dick tours which is an awesome, locally owned, and very professional excursion for snorkeling and stingray city. They do not require a credit card to reserve, and they are waiting for you right at the pier. At $40/person they take you out with a much smaller group than the ship, I really enjoyed the personal experience they give you. I highly recommend them. Thanks to Mark. We also did a little shopping but I found it was a little pricey in some places.
