We are DL vets but this year we want to try Universal studios for a couple of days. I have not been since I was a kid in the mid 80s so I basically know nothing about how it works. What are the musts for me to know with my family of 4 (Myself, Wife, MIL, and daughter 9). We found discounted tickets for the dates we are going (June) but what else do I need to look at, worry about, plan for?
