The reasons why we will stay off-site:
1. My DH and I are members of a hotel rewards program.
2. We can stay at an off-site hotel (with micro-fridge) for around $370 (plus around $84 for Disney parking or only $32 for a seven day bus pass for two adults*) for an entire week, which means we can take the parks at our own pace.

3. Having a mini-fridge means we can go to a local Costco and buy our own beer/beverages/snacks (or bring some from home with us).
4. Free hotel breakfast. IHOP and Denny's are close by if we don't want the hotel breakfast.
5. The off-site hotel doesn't have gawdy architectureal features. If I want gawdy then I'll go back to Vegas

6. Off of Disney property! I get too much adrenaline running through my system and I have major crashes.

24/7 Disney is probably not good for my health.
7. Lesson learned the easy way, I don't have to stay in a hotel to enjoy it. DH and I can hop on the monorail and have lunch at the Poly to take a break from the MK.
8. Although the moderate and deluxe resorts look very nice and appealing, they are, at best, re-creations. If I'm going to be spending big bucks on a hotel room then I'd rather go the authentic route like the Hotel del Coronado in San Diego, Old Faithful Inn, or a quaint hotel on Martha's Vineyard for instance.
My husband and I just see more value in staying off-site. We also want to visit other attractions in the area such as the Kennedy Space Center, and spend as little money on the Mouse as possible.
Lastly, I recently wrote a complaint letter to Disney (including to CEO Bob Iger) about their prices not matching the level of service they offer. WDW did actually take the time to respond to me so I don't think my staying on Disney property will bolster my complaint letter
