My first suggestion is to be on the right side when lining up for opening. We were there less than 2 weeks ago and entrance was the trickiest play. The security area is behind a building so there’s a left line and a right. The right line has 4+ security tables and detectors. The left side inexplicably has 2. The left line does not move - it was painful.
We missed most shows so I can’t speak to that except to say the dolphin show was amazing and the Sea Lion/walrus/otter show was painful.
We were there at a loooooow crowd time so the only thing we waited for was Kraken. Kraken loads slowly due to the cleaning of the VR (which I do not recommend)
