Warning, if you're easily offended by a rant, just don't read this post. I'm not singling anyone out, just addressing a mentality.
1) Disney is not expensive...it's on par with many travel destinations (actually way cheaper in many respects), includes a lot for your money, and prices increase for everything over time.
1a) Expensive is relative. Sitting at home can be declared expensive if you're stubborn enough, cheap enough, or dumb enough with your finances.
2) It's not "too hot" at Disney unless you refuse to plan during a time when the weather is more temperate. Even the "hot times" have plenty of options to stay cooler: Get in shape, do more inside the many air conditioned buildings, go to a Disney water park, or go during a different month. If it's hot at Disney, it's probably hot in your dump of a city.
3) The food is not terrible. Spend a little money and go to Ohana, Le Cellier, Teppan Edo, Be Our Guest, Chef Mickey's, etc and tell me the food is "terrible" with a straight face. Give me a break...these are the same people that think McDonalds serve great hamburgers and Chik-Fil-A has amazing chicken.
4) The lines aren't long if you use the tools provided and don't try to ride every E-Ticket at 3pm on a Saturday. Do some planning, do some research, and do some alternative entertainment available.
5) It's for kids. Ice cream is for kids too...stop eating that.
See what I just did there?
