We're good with that!
We are happy to have access to the plan, and I think it's been very good for Disney to include us. We can buy DDP year-round, with no ticket purchase as mentioned above.
The "free" plan is hardly free. It's only for six weeks in the heart of hurricane season and the hottest part of summer -- and it requires rack rate rooms and ticket purchases.
People who stay at value resorts on the free DDP get a great bargain. Most others would come out cheaper renting DVC and paying for the DDP.
There's no such thing as a free lunch...especially at WDW!
