We went that time last year, and had great weather. It was very warm during the day, but nights were cool - we even put on a jacket a couple of times. The crowds were manageable except for the weekend leading into Columbus Day. That weekend was so crowded, we could barely move. Lines were extremely long, with very long wait times. Other than that, we thought it was a great time to go. We are planning to go again at the same time, but leaving before Columbus Day weekend.
