Wife and I spent $400 at Universal Hollywood in 2017 for front of line tickets. Bought tickets at gate.
Rode every ride in the park in 1 day. So much fun. Could have been 90°, it wouldn't of mattered.
Our kids & grandkids, on their own, went to Disney last year for 4 days on their front of the line deal.
Said not so great and $$$$. My advice, if Universal Florida still has same deal my wife and I got, do it.
