Let's see, last year (all prices approx.):
$2100 for 6 roundtrip tics from Spokane, Wa.
$7000 for 2 rooms at POR for 10 days, DDP, and park hopper tickets (5 adults 1 child age 6)
$4000+ for souviners (inc. stuff for family that couldn't come)
$13,100 total.
Our Christmas trip in 2005 was about $11,000 for 10 days staying at the Contemporary (the difference is 5 people instead of 6 and during the holiday). Included meal plan, park hopper tickets,cMVMCP tickets, and - of course - Christmas gifts. Child was 5.
Our first trip (2003, 4 adults, 1 child) was about $8500 as we stayed in a crappy hotel, ate meals outside parks, rental car, park hopper/no expire tickets, and child was only 2.
We spend alot but we live on the other side of the country and like to come home with really cool stuff. Hubby has a nice leather jacket, a cool big Mickey tie-fighter figure (from SWW 2007), not to mention the shirts, pins, hats, cups, mugs, stuffed figures (pal Mickey, Stitch, Minnie, etc.), smashed pennies, jewelery (earrings, charm bracelets), pens, autograph books, and ride pictures.
We save for at least a year. 1st trip was supposed to be once-in-a-lifetime. Our Christmas trip happened because we wanted to see what all the hoopla was about and had a totally magical experience. Then we decided that my FiL would love WDW (he did!). And recently, DH began talking about doing SWW in 2009. Would also love to do the Disney cruise and MNSSHP someday. We even have Characters picked out from the movie Hercules.
But it's not how much we spend, it's the memories we make.
