Every park ticket can be used as a Fast Pass. You just put it in the Fast Pass machine, and it tells you between what times to come back to go through the Fast Pass line. You must have gotten something different than that.
Yesterday really turned out to be a nice day, although much cooler (59 degrees) with all the rain they've been getting down here and that nasty thunderstorm that came through Saturday night. We've had to carefully pick and choose the best days to do the parks because of all the rain, and we won't do weekends or yesterday being a holiday since more people are in the parks on those days.
Glad you had a good time and were able to catch some good weather in all that rain. We've been having a blast.
