Not there now, but crowds look to be super low the last two days and today.
Based on an aggregation of the various crowd calendars and Universal's one day ticket and Express Pass pricing, it looks to me like tomorrow should be low, with an uptick on Saturday, and then something between Friday and Saturday on Sunday.
Crowds will start to pick up next weekend (March 8th, 9th, 10th) and be busier than average pretty much straight through to the weekend of April 12th when they will start to hit peak levels through the week after Easter.
