Hello - We are very excited for our first Disney cruise this October. We were really hoping to do the kayak, hike, snorkel excursion in St Thomas, but unfortunately the age minimum is 8, and my son will not be 8 until January. The Disney web site would not let me register him, but I signed up the rest of my family. I am wondering if there is any chance of him getting to go along with us once we are on the ship? Or do I just need to pick something else? We are an active family, and it just seems like most of the active excursions are reserved for ages 8 and up, which is such a bummer. Thanks in advance for your input!
