I think I asked my "source" about the walk up window. I remember a response that had something to do with them getting the grill ready but they haven't set a date for reopening yet, at least the source hadn't heard of one.
On another popular topic - I have been checking the men's and women's pool showers next to Beaches and Cream everyday and they are still closed. The unisex bathroom/shower is open with a sign on the shower that said that it was not available. But someone could use this room for changing their clothes. It has a toilet, sink and bench, along with the closed shower.
Just a tip - the Beach Club marketplace has been pretty much empty and they have a much bigger selection of food than the Yacht Club marketplace. That will change when the Beach Club opens on May 30th but right now it is our preferred place to grab food.
I'm sitting on our balcony right now, waiting for Epcot to open early. We have heard that it opens around 10:10am. We are all packed and ready to go home. This is our fourth, and last, trip with Covid restrictions. This was also a very hot trip and wearing a mask in this heat is awful. It was fine when it was cooler out, like in January.
