We were there from open until close. When we arrived guests were lined up but not to worry, everyone has resos (they only leave a few spots open for walk ups). The line moved quickly. We were checked in, given the lay of land and were on our own then. The only planned thing for the day is the dolphin encounter which you will have a reserved time for and I believe we chose our time at check in. It was a little hectic leaving as everyone stays for the whole day and the locker areas/shower facilities were a little jammed. It's great day. Spend it all there and enjoy!
