It's an excellent hotel, and (obviously) a very convenient choice for a first or last night option. The rooms are large, quiet, and nicely appointed. Enjoy!
The MCO Hyatt is an adverage sized hotel that is very expensive and does not offer transport to WDW or anywhere else. I would recommend that you get a value resort on WDW property and get transportation from the airport to the hotel, this will actually be less than the cost of the MCO hyatt.
I think that most people only stay there when they arrive late or have an early flight so Disney transport is not an issue. I have stayed there when I was arriving at almost midnight and actually it was GREAT not to have to transport to anywhere.
We were there about 10 days ago and absolutely loved it. It was soooo convenient. We had a 8:15am flight and didn't leave our room until 7:15. The bellman took our luggage and even got our boarding passes. It was so nice to not have to rush.
Thanks for all the replies. We have booked it for the very reason that some of you cite - we have a very early flight on departure and very late flight on arrival back in MCO (we don't get back in until after midnight) so we booked for those 2 nights.
It sounds like exactly what we need....thanks again!!
