Yes. There was a whole line of them.....even though we were leaving right after DC closed late afternoon because of t-storms. There was usually one or two waiting outside RPR in the distance too. We had no problem at all. Try to get to DC right around 8am if you're doing the dolphin swim. That way, you'll get a morning swim time in case there are storms in the afternoon. It was really weird when we went ....Heather was our video instructor before swim....also my daughter's name (couldn't vacation with us). Hailey was our Dolphin...also my cat's name. And our dophin swim group was led by a guy that graduated from my son's high school up here! Have a great time! and if it starts looking stormy...head to the locker room right away as they will shut the whole park and make everyone go under cover! Worked out for us because we were getting ready to leave anyway, but they won't let you walk through to leave until the storm is gone. Have a great time!!!
