It's very hard for me to break it down.
We buy 10 day w/fun option and no expiration passes and we get several trips out of them, 4 or 5 at least. Because we've gone to WDW a ton, we don't necessarily do parks every day anymore. Our trips are more relaxing than the ones in the earlier days of our addiction.
We live outside of Washington, DC, and my goal is always for the three of us to fly for under $450. It's rare that I go above that. We just got back from a quickie trip, and I spent a little under $300 for our r/t tickets.
We like the mods. I just stayed at POR for $196 a night, including taxes. That about killed me because I was used to the days of deep discounts Not anymore. We do stay at the values sometimes, depending on finances.
For spending money, we spend about $150 a day including our food. I'm boycotting the DDP because I think it is detrimental to park food and atmosphere, but with the DDP we'd spend more than that anyway. I have a teenaged boy.
I LOATHE Disney's Magical Express, so we spring for a town car.
For a week, if I prorate my tickets, include my hotel, air, and spending money, I'd guess we'd spend about $3000 for a week's stay. Our trips are usually shorter, though...anywhere from 3 to 5 days.
