Universal Orlando has introduced an annual-pass deal for Florida residents that gives passholders access to its two theme parks for 15 months.

The offer much be purchased and activated by Aug. 31.

Universal recently added or upgraded some key attractions. At Islands of Adventure, the Amazing Adventures of Spider-Man ride is now presented in high definition, and Universal Studios theme park now features Universal’s Superstar Parade and Universal’s Cinematic Spectacular, an end-of-night lagoon show with fireworks, fountain-based effects and movie clips.

Opening this summer at the Studios — Universal has not announced a more exact date yet – will be Despicable Me Minion Mayhem, a 3-D experience in which guests will undergo “minion training” and attend a dance party with the yellow, goggled creatures from the 2010 film.
