The heart of Anaheim is, of course, Disneyland. "The happiest place on earth" mixes the nostalgia of some original rides with elaborate new ones, plus a 21st-century pyrotechnic extravaganza. Competing for your attention is Knott's Berry Farm, where the theme is the Old West and some of the thrill rides outdo Disney's. For a change of pace, check out the Block at Orange, an all-in-one shopping, dining and entertainment promenade.
