Will you be at Hollywood Studios during your trip? I ask because your daughter's at prime Disney Junior age, and the character breakfast/lunch at Hollywood & Vine is a fun way to meet some of the most popular Disney Jr characters. Jake (Neverland Pirates), Sofia the First, Doc McStuffins, and Handy Manny are at Hollywood & Vine for those meals. They circulate around the room for individual attention at the tables, and they do a little dance party every... maybe half hour or so?... where the kids are welcome to get up and join the characters. My son, who was 2 1/2, then 3 1/2, on his two visits, LOVED it there. I'd recommend doing lunch there - the food's pretty good (for buffet) and it's a fun experience. Doing lunch also removes your concern about not being big breakfast eaters.
If you'll be at Animal Kingdom and want to meet the big 5, I can also recommend the character breakfast/lunch at Tusker House. That's probably our favorite buffet (well, except for Boma at Animal Kingdom Lodge). We normally do an early breakfast there, before rope drop, then head right for the Kilimanjaro Safari ride to see the animals while they're most likely to be active, earlier in the morning. You could go there for lunch instead. The food is good there, and we've had very good character interactions as well. You get to do a photo with Donald (in safari gear) outside the restaurant, then Daisy, Mickey, Goofy, and I want to say Minnie(?) are circulating inside. All in safari gear - very cute.
Another alternative to a breakfast character meal would be the character dinner at 1900 Park Fare. That one's got Cinderella, her Prince, and the wicked stepmother/stepsisters. I have to tell you, the stepmother and stepsisters are AWESOME - really good character interactions with them, especially if your little girl is dressed up like Cinderella! We thought the food there was pretty good - good enough to try the same place for breakfast (with Mary Poppins, Alice, and the Mad Hatter) on our next trip!
I haven't done Akershus - the food isn't my cup of tea, and princesses aren't my son's. But I do know it's popular, and lots of people on these boards recommend it. I was rather unimpressed by the Crystal Palace food, but if your little one likes Pooh & friends, that's the best place to meet them. Again, not so much of an interest for my son, so that's one we're happy enough to skip.
(Truly, any character meal is more about the experience than the food, but I like to at least feel like there are things I'm happy to eat, since I've paid so much!)
On meet & greets: You can meet the characters (many of them) at various meet & greets in the parks. They're great. But there will be a line for each one (Anna + Elsa's line has been upwards of 5 hours long sometimes this spring!!). You can use some of your Fastpass+ allotment on meet & greets, if you'd like - that will help with wait times. There's a website that I've seen recommended here a lot, that I will be consulting when we go to Disney this fall. They list all the characters and where/when to find them in the parks.

I hope that helps.
