Mother/Daughter Disney Trip Advice!

Right! Now you're in my wheelhouse.

Magic Kingdom - This park doesn't currently have tiered Fastpasses so you can have what you like. Personally I would book a FP for The Seven Dwarfs Mine Train and Space Mountain for lunch time. When you arrive go to Peter Pan while the line is short and then head over to Splash Mountain and Big Thunder Mountain which will also be quiet at that time. As for the other FP well whatever you fancy. If you want to meet a character do that with the Frozen babes usually going fast.

Epcot - Has a tiered FP system. Assuming it's gone back to its original format before Sorin' closed for its update you want to go straight over to the Test Track and get in the standby line. Then have FP for Sorin' and Mission Space and then whatever. I would NEVER stand in the Sorin' standby line but if you do and get a Test Track FP you have to do it first thing. The tiered system means you can't get a FP for both Sorin' and Test Track

Animal Kingdom - Not a tiered system. Go straight to the safari. Then book a FP for the safari a little later as the animals move around and you never know what you'll see each time. Get a FP for the Rapids and Expidition Everest. You can add one for Dinosaur afterwards. The Finding Nemo, Festival of the Lion King and Its Tought to Be a Bug shows are also good.

MGM or Hollywood whatever - Back to a tiered system. Personally I would go straight on Rock n Rollercoaster and then head over to Star Wars and do that as many times as you can. They use different combinations of videos so you may get a different story each time. At the moment because of The Force Awakens you get the same middle section every time but that is changing again soon. Then get a FP for Toy Story and one for The Tower of Terror. You can't get one for Rock n Roller and Toy Story because of the tiered system so you need to do one first.

Thankfully with the recent changes you can make additional FP selections on the app on your phone. It's quick and really really easy. The best part is the moment you've scanned your Magic Band or card at the FP scanner and joined the queue you can instantly book your next FP while you wait in the line, you don't need to wait for the FP time window to close. This is an awesome addition. I take screenshots on my FP selections so I know what time to book the following year if they'll be of any use.

Ooooh yes, the preordering breakfast thing!  I see that in my confirmation email.  July 18th I can do that.  I should set a reminder on my phone.  So if I want to be there that day at rope drop, what time do I leave the hotel?  Is there a bus?  I'm so clueless.  I should look at their website for Art of Animation and see what it says.  

And if you want to know the best Star Wars things to do, I may have a little experience in that area.

Never been to Disney...but my friend stayed in the AofA resort, Little Mermaid section 2 or 3 years ago over Christmas/New Year's. Her kids were 2 and 6 i think. She found the Mermaid section to be very far from the Main building with the food and drinks and far from the buses, etc. but that may have been her feelings where she was dragging kids with her just to grab a refill, it was crazy busy, and she got caught in rain a couple times going to the main bldg. Nicely decorated though and newish. Sounds lovely there from what I've seen.
Following all the advice here for the next/first time we go!

I don't know if Art of Animation is one of the value resorts, but the one we stayed at, which was value, was supposed to be the only one with a dedicated bus line.  The Pop Century Resort.  The busses are supposed to go directly from the resort, to whatever park is the destination, without stopping at other resorts first.  You might want to check this out/consider it.  The room was small, but we didn't spend time in it anyway.  Didn't use the pool either, so can't comment about it.  But it might be worth a call to see if the bus thing is still the case.  I believe at the other value resorts, the busses stop at other resorts on their way to the parks.  

Good luck.  Anything you do will be fun!  Will it just be the two of you?

I've only been to Magic Kingdom and Epcot but I would also recommend Splash Mountain at MK if you don't mind getting a little wet and Soarin' at Epcot. It was just the California version when we went but I'm sure it's still a great ride.

I seem to remember that at AoA, the only section that has standard rooms is the Little Mermaid section. All the other ones are just family suites. But double check that to be sure.
