Welcome to the OI Universal Center!

Prepare to upgrade your adventure to Universal Orlando Resort with our obsessively updated collection of Universal insider information and expert advice.

The OI Universal Center is home to our free next-generation encyclopedia of Universal Orlando vacation-planning information. It contains over 200 pages covering Universal’s theme and water parks, hotels, and more. In addition, we offer our readers six extraordinary advantages over traditional guidebooks and other websites:

  • Nearly same-day updates to our insider information as changes take place in the parks
  • Comprehensive analysis of all construction projects and anticipated resort developments
  • Immersive multimedia, including more than 10,000 full-screen photos and hours of HD video
  • Intense, first-hand coverage of annual events with advice written based on this year’s activities
  • Over a thousand “real guest reviews” of Universal’s theme park attractions and dining venues
  • In-park photo updates broadcast live from Universal Orlando each and every week

Last year, over three million families used our website to plan the perfect vacation and gain complete confidence in their knowledge of the parks. As we now celebrate an even bigger and busier year, we are very proud to take our place as the premier independent resource for guests visiting Universal Orlando Resort.
