We are here now and yes, it is super muggy. More so than I expected it to be ... and we were in Cancun in early August and had thought THAT was muggy. However, we were also just sitting by the pool most of the day ... not walking miles upon miles to get from show to ride to show to ride. Today, we were at AK and it was quite humid where pretty much everyone is just glistening (or more) from sweat. However, we were able to go to Kali River Rapids three times in a row, between 3-3:45 pm. Lucky me, I was in the "wet seat" all three times. Believe me, I cooled down! After that, my two older girls were able to walk on EE for two rides (and they had already ridden twice that morning, before 10 am, with a five-minute wait each time). Everyone was told to just go thru the FP+ line b/c the Standby time was posted as 0 minutes! So, yes, it is muggy but it is not "awful" or "unbearable". BUT, the short wait times sure make up for it!
