Gee, jindy, is that all you want to know?
Let's see.....IoA or MGM.....
IoA has Spiderman, which is awesome and I'm sure you'd both enjoy it. They also have Suess landing which is fun, but not awesome at all. You could find lots of other things to do that would fill the time, depending on your interests. I enjoy the Comic Strip Island and even the Super Hero Island, but not enough to stay all day. Jurassic Park has a couple things to do, and the Lost Continent Island is OK too. The themes tell you about most of the island.
MGMdoes have SciFi, RnRC and ToT, and tons of other things that would fill the time. MGM is mostly shows, rather than rides, (except the rids you've named, there aren't many).
My opinion only, if your daughter isn't tall enough for the thrill rides, you could do either in a day, easy.
Staying on site is SO much a personal choice. We plan to, because we wanna get the most of our stay each time with Keith's Mom. Her health isn't the best, so we don't go traipsing around too much. Pick a few things and do them and others close by.
DCL transfers are also a personal choice. When Keith's Mom, Etta, and I did the Pink Ribbon Cruise, we took the transfers, and enjoyed it a lot. Unfortunately, or fortunately depending on your personal preference, we only had 8 people onboard, so it was pretty dead. I'm guessing its a hopping bus when you get it full.
Pop Century and All Stars are the most economical, and therefore fill up the fastest. $60-70 a night should do it. I, personally, think the hotels out by the Port are overrated, but we've never stayed at RonJon's, or driven our own car to need parking. We've either done a rental car we could return out there, or taken the DCL shuttle.
DCL picks up at several hotels, but as far as I know NOT the value resorts. They will pick up at AK, but if you aren't planning on a 2nd day at the parks, that wouldn't work for you.
We're planning on a rental car and planning to leave to get out to the Port decent time. Of course, if Disney does something completely wacky and allows us to book Palo and the spa early, we could plan on going later. The DCL busses only pick up starting at noon, again as far as I know, so if you want to get out to the Port earlier to look around and stand in line (not a bad thing!) other arrangements probably should be made.
I'm not sure how much room we'd have luggage wise, but carpooling is always an option. We can start chatting about carpools or shuttles if you'd like. We'll probably be staying on the monorail route just for convenience for Etta and her wheelchair, but they could pick up at other hotels.
Something else to think about!!
OK, I've had my internet time today....I'll let someone else share for a while!!

This is WAY longer than I expected!!! TTFN!
