The Long Center garage is usually closed. It was open for the July 4th fireworks display - people were up there by the hundreds, but last Monday it was closed again. You pretty much have to catch it open whenever there's an event going on, and with Covid...
The Hyatt garage is also mostly off limits. I've been run off there the last few times I've gone, and I did sneak back up there on Monday, but they have the top level blocked off with two SUVs. I did some inaudible cursing and took a photo out the side from the 2nd to the top level. They even have a sign that says no photography, even by hotel guests, and that you'll be escorted out.

I wonder what big wig nimby at The Catherine paid for that BS.
