Do the restaurants' prices increase every year?

[Fintastic]

We're trying to figure out if the DDP is worth it for us for our trip next year. Can we go off the 2006 prices or will they change for 2007?

There's no way to know. The prices do increase over time, generally in synch with the rate of inflation for luxury items (so they'll increase more than the broader rate of inflation in "good" years and will increase less than the broader rate of inflation in "bad" years).
