     MONEY-SAVING TIPS FOR DINEY WORLD

     Every time you visit Disney World, there's something new to see. What began in 1971 as the Magic

Kingdom now includes the high-techs movie-mad Disney and Animal Kingdom. Each time the park expands

(扩大), so do your chances to spend money. How can you save? As a family guide to Disney World, I've

developed a few money-saving plans. 

     ■ Buy the five-day All-in One Hopper Pass (入场券). Even if you're visiting for fewer days, it's a deal

(the pass costs $ 229 for visitors ages 10 and up, $ 183for kids ages three to nine and is free for kids under

age three). Without the pass, you'll have to pay separately for Pleasure Island and the water-parks. A single

trip to Blizzard Beach, for example, would cost a family of four $ 100.

     ■ Dine out at lunch. The prices at some of the nicer restaurants, especially those in Epcot's World

Showcase, are much lower at noontime than at dinner. It's wise to make reservations (预定) before you

leave home. Call 407-W-DISNEY. 

     ■ Become a Gold Card Member, For $ 65, you can get a Magic Kingdom Club Gold Card (call 1-800-56-

DISNEY), Card holders get up to 20 percent off Disney hotel rooms, plus price breaks on character

breakfaster, theme park (主题公园) ticket and goods from Disney stores, 

     ■ Don't pay extra to see a character. Character-theme dinner shows are expensive, costing a family of

four about $ 140.and even a character breakfast, where Mickey or Donald Duck joins you for cakes, can set

you back $ 50. If your budget (预算) is tight, try to meet the characters inside the theme parks and at free

in-park shows. You can watch the Diamond Horseshoe show, for example, in the Magic Kingdom for no

additional cost while the similarly themed Hoop-Dee-Doo Musical Revue requires expensive tickets, 

     ■ Wait until the end of your trip to buy souvenirs (纪念品). By then, the kids will really know what they

want, and they won't waste money on expensive things.
