I really need to step away from the Disney planning sites!
Stitch Kingdom posted news yesterday about the first confirmed January rehabs - BTMRR is going to be down, as expected, but Dumbo will be closed too!

The closure is speculated to be for the move to the new location in what used to be Toontown, and it will reopen just in time for the Presidents' Day/Mardi Gras week. I know Boo will be disappointed that it is closed, but more than that I'm thinking that the reopening might be a clue as to when the first phase of the expansion will open, which we'd all be excited to see.
There's a crazy little voice in my head that actually had me look at changing our dates to be there when it reopens.

But DH has some anxiety issues when it comes to the kids and crowds, and all the prices are higher - room, airfare, even dining since part of that week is peak season - so it is really just a passing fancy. Boo will have to make do with the Magic Carpets, and we'll see the new Fantasyland when it isn't packed to the gills!
So to distract myself from the temptation to try to make the later dates work out, I've turned my attention to our day two plans instead.
I love being able to both start and end a trip with the Magic Kingdom, and the park hours worked out just right for doing that this time. So on our first full day in the World it will be straight for the heart of the magic!
I've been going over how we do the parks in my head, trying to think of what I would do differently with Uncle B in the mix since he is essentially a first timer. I'm not used to that - I've adapted my planning to my family's been there, done that, will be back soon approach to Disney and we don't worry about fitting everything in the way we used to.
I want to be there for rope drop for sure, because I've never seen the welcome show.
Once we're actually in the park... Well, I've kind of waffled about that. No Dumbo and no Thunder Mountain really messes with the Touring Plans and Tour Guide Mike touring advice, and I don't want to make things too structured this first day.
I think the first stop will be Tomorrowland.
Space Mountain is a must-do, of course, but what I'm really hoping for by starting the day here is the opportunity for several rounds of Buzz Lightyear while the lines are short. B is a video game nut and Stitch is already looking forward to seeing who wins between the two of them.
I suspect I might regret it because I have a hard time with spinning rides and for some reason the height makes it worse than its land based cousins, but with Dumbo down we're going to introduce Boo to Astro Orbiter for the first time. If I'm not too busy trying to ignore the going round in circles aspect I might even slap on my zoom lens and get some aerial shots of the park.
I'm sure the kids won't be able to resist stopping in to visit their favorite monsters while we're in the area.
And I suspect Stitch might insist on seeing the stinky little animatronic version of himself too, especially since B has never seen it. I'll sit that one out. Boo is too small for it and I'm just not a big fan. That'll be a good time for Boo & I to stop and visit with a character or two.
I would like to have Tomorrowland pretty well done before we head back to Main Street for lunch. We're skipping a couple of the classic-but-not-exciting rides like Carousel of Progress and Tomorrowland Transit Authority, simply because Pocahontas and I are the only ones into the whole "history of Disney" angle and we got to ride them in March.
Lunch is at Crystal Palace.
We've been there once before, for breakfast on our Christmas trip. Shocked is an understatement for my reaction when Stitch told me we had to go back, so we're trying lunch this time. And of course Boo has a cute little outfit just for the occasion.
After lunch, we'll head for Adventureland. The girls will want to meet Tink in her new spot, and Jungle Cruise and Pirates are must-dos for all of us.
Boo will certainly want to ride the carpets and maybe stop in to meet Jasmine & Aladdin. If the big kids want to check out the treehouse they can do that while DM and I take Boo to see the characters.
I would like to see the Enchanted Tiki Room because I've never seen the original version, just the "Under New Management" edition.
By the time we finish up Adventureland it should be mid-afternoon, the warmest part of the day. This is by design because next up is Splash Mountain and short of near-freezing weather I don't think there will be any talking the kids out of it! I'll keep an eye on the Lines app through the day to decide if I need to run over there to grab FPs or if we can get away with going standby. DM will likely take Boo over to see the Country Bears or to meet Woody & Jessie while the rest of us do Splash.
That's as far as I'm hoping to get for the day. After Splash we'll hop on the train and head out. We have a 6:20 dinner ADR for Citricos, which is the only signature restaurant I haven't yet gotten to try so I'm really looking forward to it. I'm not worried about catching Wishes - we'll do that on our second MK day.
After dinner, we'll head back to the park for a little evening fun. I don't really have a plan for the evening; we'll just pick a direction and hit whatever sounds like fun. I really enjoy the Jungle Cruise and Splash at night so maybe we'll head over that way, or if the crowds are clearing out fairly quickly we'll head to Fantasyland instead. Even with evening EMH the park closes at 11, so it won't be a super late night.
