Pxydst welcome to what I think are the most fun parks ever. I love the Universal experience and that's what keeps me coming back time after time.
As noted above the RPR, HR, PBH are the 3 resort hotels onsite that offer the Express pass with your stay there. Cabana Bay is their budget resort and it does not offer express pass. But ALL resorts offer early entry to the park that is having early entry on the given day you are going.
Cabana Bay is the newest resort and it is beautiful and one of the nicest budget park resorts I have ever scene. Each resort is themed. Go to Universal Orlandos official site online and you will be able to read up on all the resorts, look at site maps, see all restaurants in the parks, resorts and City Walk.
Each Park regular usually has a resort favorite they like. Mine is the PBH. There is a new resort coming summer of 2016 called Sapphire Falls, as well as a new water park Volcano Bay projected for summer 2017.
If possible I would stay on site at either PBH, RPR or HR so you can get your express pass included in your stay. You can walk to the parks from these three resorts or take the boat water taxi over (it's free for the guests). PBH would be the farther walk. You have to walk from Cabana Bay or take the bus over (which is free to guests). I would suggest staying longer if you can so you can really enjoy the parks.
You will need a park to park ticket to be able to ride the Hogwarts Express between Hogsmeade in IOA and Diagon Alley at Universal. This is a must do for Potter fans.
The food is very good at both parks and city walk with a lot of options. You are able to go to Universals site online and look at all the restaurants, menus and prices.
For the Potter fans a meal at Three Broomsticks in Hogsmeade or Leaky Cauldron in Diagon Alley is a must. My favorite is the Three Broomsticks. Also a butterbeer while out strolling. In either Potter park. Also another nice restaurant is Mythos in IOA.
Universal usually has deals at times were you can get 3 days for the price of 2 etc, a lot of people also look at
undercover tourist,
AAA and a few other sites to price compare on tickets.
Forbidden Journey in Hogsmeade and Escape from Gringotts in Diagon Alley are the two potter rides that will be busy so hit these first on early entry.
Minions ride in Universal is pretty busy too.
Check out the maps and rides online at Universal Orlando site. Have a great time
