Yes, if you have a tender port, like Grand Cayman for instance, you need to allow time to get ashore. If you purchased tour excersions through the ship, they will make sure you get off first to make your excersion, but keep the time it takes to get back to the ship after your tour if you decide to walk around town for a bit. They will always state in the cruise compass what time the last tender is leaving shore, so be sure to take a watch and have a wonderful time. My daughter did this cruise and loved it.
