I would definitely look into renting points through a DVC member. I have rented before & it worked out really well, we saved $1100. on a studio for 6 nights vs. Disney's price. Go to the DVC Rent/Trade board and look to see who has points for rent or you can post that you are looking for points. They will be very helpful. If you don't know how many points you need, when you get to the rent/trade board, look at the very top (where the timeshare store has their ad), click onto "points chart" then click onto "points calculator". From there, you will need to type in your dates, resort & type of accom. (2BR), it will tell you the number of points you would need. Sometimes you may find someone in a bind that needs to get rid of points ASAP and will sell for $8-9 per point, but typically you can find them for $10-11 per point. This should be able to save you quite a bit.
I would then look into a DDE card (20% savings at many restaurants), I don't believe that you can get the dining add-on unless you're doing a package. The savings would be worth NOT doing the dining package, IMHO. I hope this makes sense.
