I think about the price a bit differently than often gets discussed.
To to WDW, we pay for lots of different things - room, airfare, admission, food, and souvenirs. Put together that's the price of my "Disney Vacation".
The different in the price of that vacation between a Deluxe and a Value might be 30% - maybe more - maybe less. At the end of the day, I need to decide if my deluxe vacation is worth the extra cost. There have been times that I've said - yes, it's worth it. There are times that I've said - nope, its not.
With Disney, I've learned not to look too closely at the individual costs. If they do, it will drive me nuts. $500 a night for a deluxe is crazy, but then again, so is $160 for a value. For that matter $80 for a counter service lunch and $200 for a sit down dinner for my family of 5 is pretty crazy too. So, I just figure out the big budget, decide what works for us, put the money aside and away I go.
