Can someone tell me if this is correct?
You do not have to wait 120 minutes all day. If you book at 7:00 am and get 6:30 pm you wait for 120 minutes after park opening and you can add a new LL lets say your 2nd ride is for 12:20 you tap in you can get another one right then. If your 3rd is for 1:00 you can get another right after you tap in. If you book your 4th at 1:05 for 8:00 pm then you can get another one at 3:05, which is 120 minutes past your last selection. At this point, you would have your initial pass for 6:30, another for 8:00, and for whatever time you get at 3:05. I hope this helps.
