Just wanted to let everyone know that instead of turning, turning, the lower level entrance has been shut down for renovations.
I headed over to the park on the 22nd, only to find that no group tour hosted by Tom Morrow happened. We just walked up on the right half of the exit lane to the top floor.
The lower level is to be completely reworked under new sponsorship by Microsoft.
Not sure when it will be up and running, though.
