We were there for 3 weeks and just got back last week. While we were there we did 3 character meals and out of the 3 (Tusker House, Topolino’s and Hollywood & Vine), I’d say Topolino’s and HW & V was where we had the most room around our tables.
We were sat in the centre of the room at Topolino’s where the characters come by and dance so we didn’t really have anyone else sitting around us but people were often walking by us to leave the restaurant but at no time did I feel like my personal space was being encroached on and I’m highly covid and personal space conscious. At HW & V, we were sat at the back of the restaurant by the entrance to the restrooms and only had one other table around us during that meal but there were a lot of people from 50s Prime Time and the Tune-In Lounge that kept coming and hanging around that entrance to come and nose on the characters.
Personally, I felt like at every indoor restaurant we ate at this trip (and it was A LOT) that the tables were well spaced out still and that they were still conscious of sitting everyone on top of each other but I guess things could change again before your trip. I hope you guys have a great time though wherever you end up picking!
