Ha, thanks for pointing it out because the comments are too funny! One person talks about Harry Potter being it's own park, and they want people to go to USF and the stand alone HP park.
Then people going on and on about their only interest is HP, and they don't want to do anything else so they don't want to pay more. If they would just open up to experience more, let Universal Orlando entertain them. I mean no other franchise at UOR interests them at all? There is more to life than HP, and you do not necessarily need to be a fan to enjoy their other offerings IMO.
For the train talk, it may be possible to have a 3rd train always waiting in maintenance. Then they could swap it out with one of the 2 in operation whenever needed. IDK though, just throwing that out there.
