We've stayed at all but PORFQ, which never appealed to us.
POR (Riverside) is great. Boys may enjoy Alligator Bayou side more than mansions. The pool is fun for their age, the landscaping is nice (keeps noise down), plenty of rentals there and the boat to Downtown Disney is a real plus. One of the best food courts on site. We have driven there to eat, even when staying elsewhere. We have sent many people there to stay, only to return and say it was their best trip ever. Centrally located, but buses can get crowded.
Coronado is great too ! The pool/playground "Dig Site" is great. Reasonable food by pool, relaxing with plenty of seating/cover and my kids had a blast. I've heard bus service here is good (we drive everywhere). The food court is alittle different, but if you go in, look over everything well, there is good value with good food. I've heard complaints on the tipping, we never tipped. We got our own drinks, our own food and seated ourselves....told them no tip. Was not a problem. It is a convention hotel, but while it may be full, many are in meetings so don't let that scare you.
Check above's website - it is a good one !
CBR - we will never go back. Beautiful hotel and we enjoyed walking and looking............but walk we did. Unless you are in a room close to main building, you are in for a walk. Large and spread out. We hated the food court - loud like a school cafeteria, selection poor. Pool was way too small for the size of the hotel. My boys were 9 & 4 and were totally bored with the slide. Probably great if you have no kids and you want a more beach/secluded kind of room, use of the quiet pool and are heading to sit down restaurants.
