DD9 wouldn't necessarily be talking princesses, etc at school...probably wouldn't be caught dead, but in Disney, she LOVES all the Princess interaction and the characters are so very sweet with her. She loves Akershus Princess Breakfast. They bring sausages, eggs, cheesy potato casserole & beverages to your table, then there is a pastry, fruit, cold meats, some norwegian selections at the buffet also included. A picture is included with Belle. My DH even likes it, he can be snoopy. It fills you nicely until dinner time...at least for us. It is SOOO cool to walk into Epcot & Old World before opening, too!
HDDR is a must for us. We do it on arrival night. DD loves it. We've never had any problem with the food. BBQ Ribs, baked beans Fried Chicken, Salad, potatoes, corn, Bread & Strawberry shortcake for dessert. Beer/Sangria included for adults.

It's fun, slapstick, old west humor. Very interactive.
The Dining Plan can be used for the Hoop Dee Doo Musical Revue for Categories 2 and 3 seating. TWO table service credits will be deducted for these shows. The Dining Plan can also be used for Category 1 seating at the 8:30 p.m. show, using two table service meal entitlements.
I've read recent poor reviews to Cape May & 1900..so don't know what's up with that. However, like you, I'm not too picky. I haven't found anything absolutely abysmal at Disney. (Didn't care for Casey's Corner - hot dog buns were like desert sand!)
I'd concur with Tusker House breakfast Characters as well.

Frankly, though, we always eat breakfast on AK morning at Rainforest Cafe, at like 8:30 or something. They have really good breakfasts and really good coffee!
PrimeTime is dependent on your server, I don't know how much I'd enjoy that & since my mom was such a good Old fashioned cook...we passed.
If you can snag Crystal Palace early, that is a cool walk in as well.
If we get FD we take it because we like it for a myriad of reasons...but we stay in a MOD. I always seriously consider the RO discount and think I can swing a deluxe and not feel guilty! LOL However, every family is different. You certainly could use that 30% toward food. It would be a close call.
