As long as you do a "swim" and not just an encounter, I think you'll enjoy it. Not exactly sure what the difference is in those packages. Now, if you want to purchase a CD of your excursion, they charge extra for that and it wasn't cheap. They show them to you when you are finished and if you want to buy it, you'll need to wait while they burn a CD for you. It was nice, but I thought it was very pricey. They will also offer you pictures they took during the swim.
