You might want to check out the Homewood Suites. They have a few two-bedroom suites connected by a living room and kitchen, which would prevent anyone from sleeping on the sofa bed, as long as two are willing to share a king bed (the other has two double beds). They also offer breakfast/cocktails, although not to the extent that Embassy Suites does.
There are over a dozen of Hampton Inns in Orlando, and all are good. (The one that fell below standards got booted from the system.) The rooms are standard size, yet clean, and they offer a complimentary breakfast, as well as free internet service.
Personally, I wouldn’t stay at a Radisson or Hilton. Both seem overpriced and lack in customer service, but I haven’t stayed at any of them in Orlando.
