I'm not sure how much it will slow it down. It may cut into their profits a bit because now they may have to discount rooms. I have a few reasons for saying this:
1) Disney has been great at getting people into the parks (can anyone say
free dining.) It has been one of the few theme parks that have maintained 90%+ occupancy.
2) Many folks will cut out other luxuries before giving up their vacations. I'm one of those people that refuses to go without one at least every 14-16 months. I'll eat cup o soup morning, noon and night but I need a vacation.
3) face it many, many people will charge their vacation. Not wise but I know tons of folks who do it.
4) Relatively speaking Disney is not as "out of the ball park" as any other vacation. Especially here on the east coast. A week at the shore, Ocean city NJ or Ocean city MD will easily set you back 2K-3K. My motel last July at Rehobeth Beach DE ran me $225/night (1625 for the week) and I wasn't even on the beach! My dh turned to me and said "we could have went to Disney" for a little more.
5) Gas prices have been out of control for the last year but our consumption has gone
UP!. We will not live without our cars, whatever they charge we will pay.
6) DVC is still selling strong. Rumor has it that the construction at the CR will be a new dvc property. That means lots of people who plan on returning yearly.
I'm guilty on all the above counts. I'm planning my trip to disney for '08.
