I feel the same way OP. I have seen lots of posts on these boards where people are saying that Disney is much higher priced than other places they go... but they never give the names of these mysterious places!
A week-long Disney vacation for my family of 3 has cost between $3500-4500 (depending on where we decide to stay - Moderate or low-level Deluxe - and it would be even less if we stayed at a Value). That's an off-season (winter) price, because that's when we like to go to FL. Works out to less than $200 per person per day, all-inclusive (plane tickets, hotel, park tickets, dining, souvenirs). Transportation to/from airport is free, as is transportation around the world. All shows, rides, etc. are included in the park ticket price.
To compare other vacations we've taken recently: we went to Breckenridge, CO for only 4 days, in their off-season which is summer. We ended up spending almost $5000 for this trip, even though it was much shorter than our Disney trips. The hotel and plane cost were higher. There is a small "amusement park" (if you can call it that) there with about 5 "attractions" - the only really fun one was the mountain coaster ride, the others were incredibly lame. The cost was $75 per person for an unlimited pass, or $20 per ticket for just one ride (which lasted like 3 minutes). We shelled out the $75 per person, and spent about an hour and a half at the place before getting bored. The rest of our time was spent paying $20 per person here and there for museum entrances, etc. Restaurants were just as expensive as Disney or more. Now, the mountains were incredibly beautiful, and the little town was cute. I enjoyed walking in the forest and taking in the gorgeous views, and that's certainly what you're paying for. But, I couldn't help thinking to myself that we could have spent less money and had more varied and fun entertainment at Disney.
Another comparison: We also went to Wisconsin Dells recently. This trip was cheaper than Disney overall (we live in WI, so no plane tix needed) - but the price of the tickets for the waterpark, little "amusement parks", shows, etc. to keep us busy for a day in total far exceeded the cost of Disney park tickets. We paid something like $55 per person for an amusement park (which had, again, like 6 lame "attractions" and kept us entertained for only about an hour). The waterpark was much smaller and really awful compared to Typhoon Lagoon, and tickets were about the same price.
I would seriously much prefer to explore a different vacation spot each year, rather than just going back to Disney all the time. It gets kind of old, as much as we love it. But I really can't seem to find a family-friendly, fun and active vacation spot that even remotely compares in terms of value...

All of you who say there are better and more economical options out there... TELL US YOUR SECRETS!
