We are DVC members and find that using DVC points for anything outside of the Disney World DVC Resorts and Aulani....it's just not worth the inflation of DVC points required to book elsewhere.
You can rent out your points, pay cash for your TDL hotel and most likley still have money left in your pocket to spend.
If you use a rental agency...you will of course earn less money per point. However, as noted it's pretty simple and easy
Renting them out yourself (use the Disboards DVC board) and you can earn a few more dollars per point.
