Los Angeles, California
Loved this tour!! Would highly recommend it. Our tour guide Tony was great!! Haunted House was terrifying.
Only downside is when you book through Viator you have to ring and confirm the tour in advance and choose a time . This was not highlighted when I booked the tour online and when I rang Viator to question this, the operator was really rude and condescending. For this reason i would book direct with Universal. Not worth the hassle when you live outside US.
