Definitely a situation they'll have to keep an eye on.
When it comes right down to it, theme parks won't have social distancing by their very design. The queues, which would be the areas with the highest risk of contagion, are not set up for it and the walkways aren't wide enough. However, the hope is that social distancing will not be the new norm going forward. The lockers can't be set up to handle social distancing without a cast member standing there and assigning lockers and only letting "X" number of people into the locker area.
For Forbidden Journey, wouldn't they set up the lockers to be the first thing that you go through to ease the in/outs of lines? The, as
@JoeCamel said, how do you route people exiting the ride into the same space? Hulk's lockers are across from the entrance and work about as well as can be expected. It doesn't create too much of a traffic jam with people entering or exiting. I will readily admit that I'm having trouble visualizing where these new lockers are going.
