It's difficult to advise you because of ongoing pandemic restrictions that may change for the better at any time. Not for worse again, I'm sure we all hope, though that might still occur.
CRT still has only Cinderella appearing. Recently, she began posing behind guests at a slight distance for photos again as you enter the Castle, before going up to the dining area. This is now the only view of her.
Based on our somewhat disappointing experience there in November, I'd suggest considering carefully if this brief "meetup" with her will disappoint your kids.
By the time you go, this could have changed dramatically for the better.
As for the food, I'd say neither has great food. That's merely my opinion from eating at both before the BOG prix fixe. Others rave about the BOG food, though. Looking at menus for which appeals more is about all you can reasonably do, I believe.
I'd advise deciding which you think the most appealing location. The Castle is looking a bit the worse for wear, IMO. BOG has spectacular rooms and is by far the better one-time experience, I'd say.
