are you going to Us - then would suggest one their resorts -
from universalorlando.com
Staying on-site is the best way to experience all that Universal Orlando Resort™ has to offer. When you stay with us, you'll enjoy Early Park Admission† to The Wizarding World of Harry Potter™ and Universal’s Volcano Bay™ one hour before the theme park opens (valid theme park admission required), and receive other special perks exclusive to on-site hotel guests.
Plus, guests staying at select on-site hotels get more rides, more often with FREE* Universal Express Unlimited™. So you can skip the regular lines at most popular attractions in Universal Studios Florida™ and Universal’s Islands of Adventure™, including The Amazing Adventures of Spider-Man®, Despicable Me Minion Mayhem™ and now The Wizarding World of Harry Potter™.
the hotels seem to be
the Loews hotels - expensive
hard rock
and several others
I might go with Loews Sapphire Resort it is more expensive than what you want to pay - but with the early entry it might be worth it
