If you've seen those fancy wrist bands that act like credit cards at Disney World, the theme park giant this week announced that it has expanded its MyMagic+ program to include theme-park guests not staying in a Disney hotel. In other Disney news, it will now cost you more to park there, up to $17 from its current $15. It's another in a series of price increases in recent weeks at the world's busiest tourist attraction. The MyMagic+ bands allow any visitor to make advance reservations for rides, attractions, show, meals and more. The chip-embedded wristband that doubles as admission ticket, reservation keeper, charge card and hotel-room key has been in test trials for months at the parks, available at first to only Disney resort guests, followed by annual passholders. In February Disney announced that ages 10 and up will pay $99 for one-day tickets to the Magic Kingdom, a $4 increase, making it the most expensive of all Central Florida theme parks. Prices for one-day tickets at Epcot, Animal Kingdom and Hollywood Studios also increased $4, from $90 to $94. Many visitors to the Disney parks purchase multi-day passes, which can decrease the daily cost of visiting the parks. —Sharon Kennedy Wynne, Times staff writer
