How to go from Disneyworld Olando to Universal Studio

There are free scheduled shuttle bus to Disney Theme Park
and Universeal Studio, Sea World etc. as provided by some of
the motels in Orlando, Florida. You can check the web sites
as belows:

www.orlandohotelmotels.com

Also, LYNX buses and GREYHOUND buses both have
transportation services to Universal Studio, Walt Disney
World etc. The web sites are:
wikitravel.org/en/Disney-World
mcojpn.hp.infoseek.co.jp/en//eng-lynx
Actually, you can go to YAHOO web site - search
for INTERNATIONAL- USA, tracking for LYNX BUSES
or GREYHOUND BUSES, then, you will have detailed
informations with different web sites.
If you drive, it will take only 30 minutes from Universal
Studio to Walt Disney World. I lived in Orlando, Florida
before. I can drive you there. You can email to me if
you have any questions.

Check on Yahoo map, so you know you distance from Disneyworld to Universal studio. If you don't take taxi, I think you need to drive there. You can take buses to there, but it takes you forever to get there!
Good luck!
