We actually have a reservation there this coming October which will be the fifth time we've stayed at the Comfort Suites Maingate East since 2003. Rooms are clean, spacious and comfortable, the staff are outstanding and the free breakfast each morning is a plus. Location is excellent - only a few minutes from Disney. Upon check-in there was a welcome basket of goodies and a note welcoming us back to the hotel - a nice touch. One afternoon after returning to the hotel to rest, we were greeted by a lovely towel animal that housekeeping had left for us. Our only complaint would be the slow elevators.
We have also stayed on-site at Walt Disney World and we much prefer the Comfort Suites to Disney as the rooms are much bigger and the price is quite a bit less than what Disney charges.
