We are headed to CTI in June, and were wondering about the additional excursions that are offered. We were interested in the horseback ride, and zipline. They both sound like fun, but I was wondering what exactly it entails? Is it worth it? Also the dolphin swim sounds amazing and like a once in a lifetime opppurtunity, but its really expensive. Has anyone done this? Is it worth it? I'm a bit of a chicken and not a very good swimmer, would you suggest it for someone like me? I'm a bit hestitant since its so expensive, but I really want to try it out! I know my husband would love it and I don't want to hold him back so I would like to try and go for it! Any feedback would be very appreciated!
