After reading some of the key points coming out of California in regards to relaxing some stay-at-home restrictions, I reflected on BGW and it's physical layout and it's handling of large crowds.
Trams- In keeping with social distancing, I'd assume they'd have to go to 50% capacity (every other row) to transport.
Main Entrance - In my limited exposure to various amusement parks, I find BGW to have one of the most confining main entrances at parks. You'd assume (from guidelines) touchless temperature/bag checks will occur there. To eliminate congestion, all the turnstiles will have to be open. More manpower will be needed to avoid backups.
Eating Establishments - Specifically the larger two - Festhaus and Trappers. First off, controlling the number of people in line. You'll have to space people/families apart. Secondly, you have to eliminate the "help yourself" buffet lines. TMs will have to hand you any item you may want. Seating (especially Festhaus' family style tables) are going to be a huge challenge. California is mandating restaurants reduce capacity 50%. So does BGW remove every other row of tables? And how do they limit the number of people sitting at each table to maintain a safe distance? Considering how crowded Festhaus is on a hot summer day, the challenges will be astronomical.
Ride queues - Many are switch-back. To maintain spacing, they'd have to go to a "straight line" queue. Unlike Disney/Universal BGW doesn't have a Virtual Queue system in place. So how will they control the number of people in line and maintain spacing? In some areas near rides it's rather congested, so they're limited to space to allocate for queues.
Shows- I think the indoor theatres won't happen. To limit seating, disinfecting seating areas between shows and maintaining safe distancing will be cost prohibitive and potentially higher exposure to virus contamination.
Public Areas - BGW will have to have a much larger "area host" contingent. Continually disinfecting rest rooms, benches, railings, etc. will be a huge challenge.
Rides- Every ride will have to be wiped down after each cycle. Do we'll see reduced capacity and longer load times. Some rides currently operate with one operator. To increase efficiency, you'd think they'd have to add TMs. Imagine the wait on the Carousel if the single TM has to wipe down every horse.
Public cooperation - This will be huge. Despite any safeguards and new procedures you're going to have contingents of "it doesn't apply to me" or the "FUs". It seems to me that BGW is going to have to have a much larger security force to enforce and manage this "new norm".
I honestly don't think a lot of the above is an exaggeration of what's needed but more of an anticipated expectation of what the government will require to allow the park to open. But, with expected increased manpower and (probably) reduced capacity I almost wonder if it not be best to wait it out until a vaccine becomes available.
