Universal Studios Hollywood to Offer Free Shuttle Service from Anaheim

A free shuttle service from Anaheim to Universal Studios Hollywood will begin July 1 to accommodate guests during the peak summer travel season, it was announced on Monday.
Universal Studios Hollywood has joined with Southern California Gray Line to offer the new round-trip shuttle service on Gray Line "luxury" passenger buses.
A live narrated scenic tour will be provided by a "driver guide," who will offer highlights of Southern California locations and attractions, including "behind-the-scenes" trivia from the movie studio and theme park in Universal City.
Free shuttle service will be provided to guests who purchase a full-price admission ticket to Universal Studios Hollywood through Southern California Gray Line directly or via a hotel concierge or wholesalers, and online at UniversalStudiosHollywood.com and CoachUSA.us.
The shuttles will depart from various Anaheim-area hotels twice daily, with departure times tentatively scheduled at 8 a.m. and 11 a.m. Return trips from Universal Studios are tentatively scheduled between 6 p.m. and 9 p.m. based on the season.
Admission to Universal Studios, including round-trip transportation, is $59 for ages 8 and older; and $49 for ages 3 to 7. Children under 3 are free.
