There are three Universal parks together in Orlando, Florida
1) Universal Studios
2) Islands of Adventure
3) Volcano Bay
And there is a The Hogwarts™ Express between Universal Studio and Island of Adventure. It itself is a ride too with screen instead of windows.
Two best rides I liked were at Island of Adventure.
1) Hagrid’s Magical Creatures Motorbike Adventure™
2) Harry Potter and the Forbidden Journey™
