We are planning on visiting Universal Studios on Thursday, January 18th. I assume that it will not be too crowded at the parks. I am considering whether to purchase a one-day admission or a 2-day. We planned on only visiting Universal Escape but I know my kids would like alot at IOA. Is there enough time to visit both parks when they will be closing at 7:00 p.m. Also, will the front of the line access matter at this time of year? One more thing...how do you get from park to park? Thanks for your help.
