My wife and I went to KI without the kids this year,and we bought fastlane just because of the heat. She will not ride coasters with me if its hot and she has to stand in line,so i had to do what i had to do! The lines were only 20 minutes on average,but it really was well worth the money! I was never a fan of fastlane,but it makes a hot day a much cooler day if you know what i mean! If you go to Soak City check out Pipeline Paradise,even if you dont want to ride its fun to watch people wipeout!
