Backdraft, Spider-Man, T2, Waterworld, Beetlejuice... Need I go on???
I had an extremely tough time to the point where I just gave up trying to get ahold of Japan over the phone or email in 2012. It may not happen.
I walked into Guest Relations when I visited the park and although they spoke some English, they weren't very accommodating in terms of special treatment. I stayed at the Universal Port hotel. Very small walk from the train station at Citywalk and only a one block walk to the park! My room had a view of the park and it was like I was 10 years old again looking from afar to an all new Universal experience I had never experienced before. It was a vacation of a lifetime!
I hope you are not afraid of trains. Their system is beyond imagination and massive. Extremely easy to get lost if you do not do your homework. I can give you all the info I know if you want it.
