We, a family of 5, just returned from WDW after a wonderful week at the Beach Club. We drove from upstate NY in a rented car, stayed on the 7/4 deal, and ate three meals at TS restaurants.
I will never forget this trip. It cost (package, meals, drinks, travel, etc.) almost $4,800. Best money I ever spent on a vacation. I can't afford it every year, so we don't go every year, but we can swing it every two years.
A Disney vacation is an experience that should bring a great deal of satisfaction. It did for us, and it was worth the $$$.
I agree with the posters who cite the cost of other entertainment and vacation options: in comparison, Disney is a bargain. Last month, I saw that one day at my local Six Flags park was $42. I am more than willing to pay twice as much for the Magic Kingdom as it is worth about 10x as much in comparison. However, with multi-day tickets, I am down to about the same $42.
I am saving $50 ($7.15 per day) per week starting this week for the 2011 trip. $5000 is only two years away.
