I will see if I can copy and paste the list for you here. Not sure when you are going, but if you want to look at the list for future reference,
1. go to the Disney World website,
2. click on about dining under Things to Do,
3. at the top of the page, there will be a white box that talks about the phased reopening and "Dining Reservations are available on line,
4. Under Dining Reservations are available on line, click on the link "learn about updates to dining"
5. On the new page, scroll about 3/4 of the way down. There will be two picture boxes side by side. On the left it is a picture of the castle. On the right it is a picture of 4 females on a bed. Just below those pictures it says "Theme Parks" and " Disney Resort Hotels" Click on the one you want to see dining for.
