Maybe someone mentioned earlier and I missed it, but is it just feature pools where people are experiencing wait times? Or are the other pools also affected?
If it's just the feature pools, they could figure out activities and things to draw people to the other pools. (Show a movie(/sing-along) at the pool, music, etc. There are creative people who could figure things out.) Granted, it would involve more CMs and probably other expenditures, so not sure they'd want to do that. But it *could* be done.
My kids also always enjoy the lawn activities at the Poly. Are there places they could hold similar things at the other resorts? (Put down tape to mark distancing, put on some music, have hula hoop competitions etc.)
