No, and you don't need a package, the DDP, a reservation or anything else to book dining reservations.
Dining reservations are open to all at 180 days out from the date you want to dine.
For on-site guests, you can call 180 days out and make 10 days worth of reservations. That's the only real difference (along with not having to pre-pay for a few things if you're not on a dining plan).
