When we arrive late I always get a room through Priceline near the airport. If you bid on a 3* hotel in the MCO zone you will get a very nice room for under $50 as a rule. In that zone the 3* hotels are the Hyatt inside the airport, the Sheraton Suites, the Renaissance, the Crowne Plaza and the Holiday Inn Select. All (except the Hyatt which is inside the airport) have very efficent shuttle service 24/7...so you just give them a call from the courtesy phones near baggage carousels and they will be there in less than 10 minutes to pick you up. Ditto for the return to the airport in the AM. You could easily get 2 rooms at that price. We frequently get the Hyatt inside the airport, although the other places have larger rooms and bathrooms, so I do not mind the short shuttle ride. I would start bidding at $43 and go up by $2 per bid until you hit on something (sometimes it is $45 to 48). The 2.5* hotels in that zone through Priceline are nice too (just no chance of getting the Hyatt that way)
I do not like going to a value or moderate when we arrive late because you have to wait through the rental car lines, drive 30 to 40 minutes to get to the resort, check in and then try and find a place to park near your building in the dark and lug all your stuff up the stairs, etc, etc...for a 10:30 arrival it will be 12:30 or so before you get into your room....when we stay near the airport we are usually in our rooms within 45 minutes of the time we get off the plane
