Yes, that's true, but it's nothing that they don't know already.
I always find it interesting when these conversations come up as to the relativity of cost. Does it cost a lot for a family of 4 or 4+ to fly to FLA, pay for a hotel, food and associated costs, you bet!
But in perspective, I consider Disney to still be a bargain.
As was said before, a Broadway show (x2?) is $120-200 a ticket, plus train/cab, plus dinner possibly...all for 2-5 hours.
Pro sports is $25-60 a ticket, plus $20 parking, plus $5 hot dogs and $10 beers for about 3 hours.
A beach house for a week is $2,500 -$4,000 + and there is no food or maid service included there. And prices of beach restaurants?....more than Disney, thats for sure.
Movies at $8-10 ticket plus about the same at least for food...
All other parks are within $10 of Disney, and we all agree that they do not compare.......so.....
If you ask me would I like to pay less for something, sure,
Do I expect to get something for nothing?, NO
So, other than day trips or camping where we bring everything in, Disney is in my humble opinion more of a value than most any other vacation.
