We have been the very end of May, July, the beginning of August, the end of August and in October (during the food and wine festival). The crowds and heat were more manageable in October. I thought it was far more pleasant then. This year we are going the first week in November and hope to experience even less crowds and not such intense heat. Our favorite hotel was the Beach Club, because of the easy access to Epcot, our favorite park. We liked the Poly and we have tried only one moderate, Port Orleans French Quarter. A little smaller but when we were there last October it was quiet and not crowded at all. Have fun!
