An Internet travel service that ranks the top U.S. theme parks has listed the four Orlando-area Walt Disney World Resort parks in its top five.

Travelers Advantage, a fee-based provider of travel components including air, cruise and accommodations, ranked Walt Disney World's Magic Kingdom as the No. 1 theme park, followed by the just-turned-50 Disneyland in California, Epcot, Disney-MGM Studios and Animal Kingdom, the latter three all in Orlando.

Universal Studios' park at Universal Orlando was ranked sixth, and sister park Islands of Adventure came in seventh. Disney's California Adventures followed in eighth place, with SeaWorld Orlando ninth and Universal's California park 10th.

Travelers Advantages based its ranking results on in-house expertise, citing Travel Industry of America and International Association of Amusement Parks & Attractions statistics that one in 10 American vacationers will visit a theme park or amusement park this summer.
