I'm going to Universal Studios Hollywood with my family during the week of August 14th, and we're debating whether to spend the money for the FOL passes. I've read in the reviews they are great for avoiding the long lines, but the cost would be huge for me (going from regular charge of $435 to FOL charge of $895). I've read that near the end of August through Sept kids are heading back to school in Calif so that is a slow time, but my visit date is right on the cusp for the 3rd week of August.
I'm considering going with the regular rate tickets, and once we get through the gates deciding whether to upgrade to FOL on the spot after seeing the crowd level. Hence my question: Does anyone have an idea how quickly the FOL passes sell out?
