Really enjoyable. Get there early. Queues were a pain but we managed to see everything we wanted too. Don't think my stomach is suitable for the rides though.
on June 23, we went directly to the gate, after queuing around 30 minutes to go in, we could not go in because viator sent us the wrong voucher. The lady at the gate advised us to go to the customer service to exchange the voucher. we had to queued again for another 1 hour 30 minutes at the customer service counter to get the correct voucher. We wasted 2 hours just to queue
Viator has a bus take you from Hollywood Blvd. to Universal and they pick you up afterwards with no worries about how to get there and back. The adventure was amazing. Downloading the tix is super fast and hardly no waiting. This is a must see experience.
