there will be 9 of us, adults and kids combined. 5 have never been to universal so we want to see as much as possible. we will be getting the 2 park 1 day passes. should i buy the express passes to insure they get to see everything? or will i feel i threw away $800 when we pass a short line to get to our ride? we have October 25 set aside for universal/islands. thank you for helping
