I attended the Typhoon Lagoon event this past Saturday night. Check in started at 4:00 and we arrived about 4:15. There were cast members at the front with ipads, checking magic bands and handing out wrist bands. We did't need to show out email, yellow cards or ID and a lady in front of me was ticked that she had brought it all with her. The CM explained that it was just in cease things were not linked right and they needed to verify.
Since the park didn't close until 5:00, the changing rooms were mobbed with day guests preparing to leave and most of the chairs were still occupied.
I was on the lazy river when, exactly at 5:00, the life guards began telling everyone in the river that they had to have a wrist band or exit.
The wave pool was closed for a time so that they could get everyone cleared out.
The dance party on the beach near the wave pool was a great add for the kids (and a few adults). There were special photo opportunities but, frankly, the lines were too long for me to bother.
It took DH 20 minutes to be served two beers so we did not even bother looking at the food options but everything appeared to be open.
The crowd level was pretty good once the park closed. I think this was most evident int he wave pool.
We left at about 7:30 to go back to the resort. Only us and one other family on the bus. The buses to Disney Springs were a madhouse since that is where they told everyone to park. Disney was loading two DS buses at a time though.
