ruadisneyfan2 thats some helpful information for the Hyatt. I would love it if we could get a room there for the night of Oct 15th,
it would be so much easier than taking a shuttle back and forth to an airport area hotel. 
Once you try it, you'll be amazed how convenient it is! I had even considered seeing if I coudl get a room at a value or even a moderate with a discount or something for that first night, but I figured it would be a pain to move our stuff at Disney.
I tried to look on Hotwire and LMT but couldn't tell if it was one of them. There was one I thought might be it, but it was $158.
I use priceline a lot for hotels when we travel so that was I was going to do for this night. I can usually get an airport area hotel (3*) for $40 or so in Richmond and was hoping to get a similar deal down there. But I would be willing to pay a bit more even $100 or so for the convenience of staying in the airport.
I checked Oct 15 on LMT. I enter MCO to start my search. On the next page, I check "airport area" only. then sort results by 'star rating'.
The top of the list is a 4* for $111. Click on "photos." There should be 5 thumbnails:
1. 1 bed in hotel room
2. 2 beds in hotel room (very easy to recognize as Hyatt for past guests.)
3. pool with green lounge chairs and fountains shooting out of wall into pool. This is def the Hyatt's roof top pool. My kids loved it!
4. lobby area/check in desk. also easily recognizable to past guests.
5. one of their restaurants.
It states it's 3.84 miles to airport but I think if they said 0.0 miles, it would be a dead giveaway.
Right now, it's $111.48 + $17.28 taxes for a total of $128.76.
The Hyatt is not so easy. For our cruise in March, it never did become available for our date. It either shows or doesn't, and there's no way to make it appear.
Search MCO for your destination. Enter 2 adults, 2 kids regardless of the # in your party. Hyatt is the only 4* in the MCO region with a trip advisor rating of 4.5 out of 5 green circles and recommended in 95 % of Hotwire customer reviews. To see the Tripadvisor rating, click on the red continue button as if you're buying that hotel. The next page will show an area map. Just scroll down past the map and you'll see the little owl logo and that hotel's TA rating. This part is very important. The only other 4* in the MCO area is the Renaissance by Marriott and its TA rating is 4.0/5.
I've never gotten the Hyatt more than 1 month in advance. Once, it didn't show up until 1 week prior. I always book a cancellable reservation as a back up. I booked through LMT for our Sept cruise and they do charge a $25 cancellation fee if >7 days prior so Hotwire will have to beat LMT's price by more than $25 for me to switch.
If you want to "see" what the Hyatt looks like right now, search for this Sunday, July 17. 2ad/2ch. Right now it's showing at the top for $60 + tax. $72.97 total. It's almost always there on Sundays.
Good luck! If you have any more questions, just ask!
ps. I wouldn't stay here if you have an early afternoon arrival. There's not much to do, after all it's an airport. For late arrivals or early departures, it's so sweet!. One time, our 9 pm departure time from Philly was delayed due to severe T-storms up the whole east coast. We didn't take off until 12:20am. Boy was I glad we had the room at the Hyatt. Kids & I were delirious at 3 am.
DME has nothing to do with luggage getting checked. That's RAC.
