Just returned from a UO/WDW trip (Sun-Wed) and found Universal to be more crowded than I expected. Now mind you, I'm very sensitive to crowds and long lines, but I had been reading on these boards about the relative lack of recent crowds. It certainly wasn't like summertime or the holidays, but we were grateful for Universal Express via our stay at the Hard Rock. The more popular rides in each park had 20-30 minute waits at midday and late afternoon. As at anytime of the year, getting in early is key...we were able to breeze through rides for the first hour or so each day. By the way, we also went to Epcot and it was jammin....Soarin had 70 minute waits and Test Track was at 40 minutes.
Seems like there was a disproportionately high number of folks from the UK in attendance, so perhaps there were school holidays or something else going on.
