Well, we're back and had a great time! Yes, I'd go again with my sister and her kids, we loved it.
The Walmarts around here are all open on Thanksgiving, but they are madhouses, and I know that they won't have swimming suits. My neice used my daughter's old suit, so that worked out.
This was what we ended up doing most days: I would be the first to awaken, I'd get ready to go to the parks, and leave to get coffee for myself. Return to our room, waken my 14-year old daughter and the two of us would leave around 8:15. We'd be at our chosen park around 8:30. Rope drop at about 8:45, for a 9 o'clock opening, (we never used the EMH park) and we'd ride the headliner rides.
My sister would be awake when we left the room, and usually her kids too. It would take her THREE HOURS from the time they were all awake, to get herself and the 2 kids into the park!! They usually arrived at 11:00 at least. As a result, they only got to ride about half the rides we did.
She just made me realize how important it is to be organized on a Disney trip. She kept doing things like stopping to admire a little girl's hair. Meanwhile, I'm scoping the scene, seeing a HUGE group of teenagers coming in our direction, all heading for the same ride we are, and trying to tell her, "let's get in front of these kids," but because she stopped to admire the little girl's hair, we were then behind the group. But I'd just shrug, exchange a smile with my daughter, who realized what I'd been trying to do, and we'd ride. My daughter and I kept giggling at how they were like Dug from "Up!": they'd see "something shiny" and totally forget what they were doing. LOL!!
She kept telling her kids things like, "We will do whatever you want to do," and then "Well, it looks like we can't ride Toy Story Mania," when the line was 90 min. with all Fastpasses gone. (I literally gasped in horror when I heard her tell her 5-year old he could do whatever he wanted--who tells a kid that??? EVER????)
Ultimately, we had a great time, her kids had a great time, and yes, I'd go back with them, because we had so much fun. A condensed trip report will follow.
