For anyone curious, I went to Universal this evening. The low waits on the app and the empty pictures I saw online were enough to entice me.
5:30 arrival into Universal Studios. Grabbed a Gringotts virtual queue at 5:25 good beginning at 5:40. Walked right into Gringotts with no line whatsoever, we skipped both preshows. I sat in row 1 and another single rider sat in row 3, that was the entire car.
Walked straight into ET, I sat in row 3 while two others sat in row 1. There were 2 entering behind me and that was it.
Used my Express Pass for Mummy, which wasn't really needed but hey. I was the only one in the Express queue and had my own personal Mummy ride. Finished it off a few minutes before close with my own personal ride of MiB.
It was raining pretty good the last hour which likely contributed to the low crowds, but it wasn't even close to the level I saw for the AP days. I'm interested to see how the weekend goes but it was so good to be back and get my theme park fix.
