We went the same week last year. The hotel was fully booked due to the free dining plan, but the parks were never overcrowded. I would recommend ponchos, it rained every day at somepoint sometimes on and off and sometimes a couple of hours. But we still managed to go to typhoon lagoon for a day, some time at the hotel pools and we managed to see everything in the parks we wanted to and enjoyed great meals I would definetly do it again!!!!
