when we went to DHS last year, DS was 2. We arrived at or near rope drop, and did in no particular order, Toy Story, Muppets, character meet and greets (several - Cars, Donald, Chip/Dale, Jake, Sofia, maybe another?), DS and I went to Disney Jr while DH went to Star Tours, had a snack, did some shopping and we were done, I think around noon. DH wanted to go back on Toy Story but there was no way.
This year, I said we should skip going to DHS, DH wants to go back for Toy Story, so we will do another morning, probably Toy Story, character meets, Muppets, Disney Jr show. I hope to cap it off with an early lunch at Sci Fi and then we will be on our way. Maybe Frozen? DS likes some of the songs.
I like RNRC but not enough to go alone, neither DH nor I will go near TOT. Last year we were hesitant to bring DS to LMA (noise) though he loves cars, same with GMR (thought it would be too scary) - I still don't think GMR would be good for him.
