We are a family of 4 and I do foresee going to WDW for years to come (and can see the DW and I to continue going even after the kids fly the coop). So because of this.. I am thinking I should do DVC.
We've stayed at all types of resorts (Contempo, Coronado, All Star, Shades of Green, several of the places in Lake Buena Vista and offsite apts). Are studios in DVC comparable to a moderate room? Or are they nicer?
Do you think I should rent points to "try it out" before buying?
As an alternative was thinking if I should just buy a condo offsite (with Fla housing prices, they seems to be a good deal).
We're also a family of 4. DD is 15, DS is almost 12. When they were younger, it was easier to do the smaller room. Now we tend to get 2BR's so they each have their own (real) bed and more important with a teenage daughter, the 2nd bathroom!!!!! I will warn you, once you stay in a 2BR you'll never want to go back

Even after the kids are gone, DH & I will stay in 1 BR's for long trips and studios only for quick trips. We enjoy having the living room as we spend a lot of time at the resort. I don't use the kitchen for cooking, but we do bring our leftovers back to the room & have breakfast/snack items there.
DVC studios are comparable to a regular Deluxe room except that you don't have the 2nd real bed (OKW being the exception). DVC studios have a queen bed and a full size sofa sleeper and a mini kitchen. We've stayed in a studio once (our DVC trial on rented points) and it worked. It was nice to have the sofa, to sit around and easy to pull it out & put it away. The issue for us was a girl/boy that won't share a bed (eww

) so we had to have an aerobed as well and that took up space.
Would you be happy staying offsite? You may get a better/cheaper deal that way. Personally, I won't stay off site (admitted resort snob

). I like to pull up to Disney and not leave the magic all week. I don't want to drive, I don't want to see the real world. So an offsite timeshare/condo wouldn't work for me, but it might for you.
DVC is great, but it's not the right answer for everyone. You'll need to look at what's most important to you now & in the future, will you want/need larger villas, are you willing to drive to & from the parks, will you continue to go to Disney every year/other year, what about after the kids are gone? Even if your kids are small now, they'll be out of the house long before your DVC contract is up. We only have 6 more years till the "baby" is out

DH & I can't wait till we can do more trips per year; Food & Wine here we come! Flower & Garden, can't wait! Winter golf trips

We'll use & enjoy our membership as much if not more once the kids are gone, will you? It's a lot to think about

and took us several years to decide that it was right for us. Our last cash trip was on rented points at SSR, we did the tour (again) on the 1st day and signed the contract 2 days later. After doing the math over & over & over again and then seeing DVC in action, we had our answer
