I am confused. The OP addresses all of your questions in detail.
I think all of the confusion came from Disney - for AG and WCT, their website just says "Disney Dining reserved viewing ticket" but for CCR it says "receive a World of Color Center Stage Viewing Area ticket." On top of that, when I asked the cast member on the dining reservations line about this, she said there is a separate area for CCR customers, and it is the best view of all the options. So I just assumed they were right and this info wasn't on here yet.
So, I'm guessing the CCR queue area is exactly the same as other diners, and the only difference is where they will point me to go when they look at my ticket? If so, I'll probably try AG as even though the cast member told me CCR was appropriate for a 2 year old, I have a feeling AG is a little better. I do want to dine, plus we will be over at DL all morning until they close early at 5pm that day.
One more question - how hard would it be for me and one other person to save a spot for my wife, 2yo, and 10 month old until 30 minutes prior to showtime? Will they be able to get through the crowds to us?
Thanks for all the help.
