Which park is HP in?

[The Princess]

We have never been to Universal before always staying at Disney but next month we are going over to see The Harry Potter park. I am a bit confused about the park...is it one park or 2 parks? We plan on only going to see Harry Potter so which park is it in? And how do I purchase tickets?

The Wizarding World of Harry Potter (WWoHP) is one of the several themed islands in Universal's Islands of Adventure (IOA). Universal Orlando has two parks: Universal Studios Florida (USF), which everything is movie themed and is considered the more "family friendly" park. IOA is divided into 7 themed lands, each with their own story and intricate details.

Ticketwise, there are deals everywhere. You can get better discounts on multi-day tickets than if you were to get a 1-day/1-park pass.
