We travel with large groups, 10-12. I've found that lots of the outdoor QS tend to have tables that do not move.
But indoors, if they have those square tables, you could push them together.
(ie abc-commissary, sunshine-seasons, village haus, and restaurantosaurus are common for us since we have always been able to find seating for 10-12, even when busy).
Pre-covid, obviously. Last week, I found that they thinned out tables at most places, and put signs on tables that could not be removed. CMs are very accommodating, but Disney officiallay has said that large groups "should be broken into smaller groups"
