My family went to typhoon lagoon on Sunday during the first week of June. We had a wait of approx 5 minutes for the slides up until around noon. After lunch, we experienced longer waits, and rain. Try to be there before opening to get a covered picnic area, and to ride the slides with minimal or no wait. The crowds really didn't present a problem with the wave pool because it is huge. You probably will want to try the snorkeling with the sharks attraction as early as possible because crowds cause this line to back up on even less crowded days. Have a great time!
