I'm taking my wife to Disney World this Fall: her first trip ever and first vacation in Florida. We're making plans now. We're doing the whole shebang: Disney hotel, meal plan, multi-day pass with parkhopper option. One specific question: How are the crowds on over the Labor Day holiday weekend? We can go that weekend or a bit later. My goal is avoiding the crowds. Anything tips to share with Disney novices? Any must see attractions that I might otherwise miss? Secret codewords to get free upgrades?
