Probably the wrong time of year for the Front of The Line Pass as crowds were down and the lines short. The visit was good once we got past the front gate, Having brought the tickets beforehand didn't save us the line up. The girl at the "Will Call" gate served everybody so took us just as long to convert the voucher as it would of to buy the ticket.
We (3 adults) had only one day to experience Universal Studios. Our passes were collected at the park by presenting our pre-printed Viator voucher.The front of line passes were fantastic. The park was busy and our passes meant we simply went to Gate A at each ride or show and were 'on board' or seated in a very short time. We were able to ride our favourites on multiple occasions.
I can thoroughly recommend both Viator and the front of line pass.
It was definitely fun and enjoyed every moment thoroughly. The price is plentiful and I wish it could be lower to allow everybody enjoy a day at universal studios but I think it is eye opening to see how people are deceived with studio made movies and believed in totally producers' imagination.
