Awe!!! Happy birthday to Peyton!!!
As for your dining reservations, I think they look good considering the popularity of that time of year. Here is what I know about the restaurants i've eaten at before.
Boma is one of our FAVORITES!!! Absolutely fantastic food! If you've never been definitely don't cancel and go give it a try!

Cape May Cafe for breakfast is alot of fun. It is character dining and the characters are in fun beachy costumes. I really liked it for that. The food is like normal breakfast food but if you're going to see the characters then I say keep that one too.
Whispering Canyon is another one that DH and I really enjoy. The WL is beautiful and just being in that resort is enough to keep us going to that place. We always get the all you can eat skillet thing, which did change a bit with pricing but regardless I loved the food. If you like BBQ and you don't mind doing the hokey pokey you and the family will enjoy it!

We have done Ohana for breakfast too. I personally liked Cape May's better (I know DISer sacrilege

) but if you're going for the character experience and you don't mind run of the mill breakfast food then go for it.
The rest i've never been to... But I hope this helped!
