I am new to this also and DH and I will most likely buy a resale at BWV next spring.
I have learned so far, before I answer with what I already know, that the BEST reason to buy
DVC is because you want to stay at your HOME resort often. That is the best use of your points. Actually any DVC resort is the best use of your points. Staying at your home resort is the ONLY 100% guarantee since you can book it 11 months out.
That said...here are the perks I know of:
-AP discount of $100 ($125 off of Premium AP)
-some food discounts (i.e., 10% off at Ghirardelli in Downtown Disney)
-free valet parking at DVC resorts
-same benefits as anyone else staying on WDW property (EMH, transportation, free parking, etc.)
-the ability to purchase the
Disney Dining Plan (any of the 3 plans) for the length of stay for each member of your party, but a ticket package is NOT required
-$4 off per adult and $3 off per kid at DisneyQuest or the water parks (if not included in your ticket and you go separately)
There are others people have told me about but I forget right now. These are the ones that stick out in my mind!!
People have also mentioned...DO NOT buy DVC simply for the perks. Buy it for the right reasons so you will not be disappointed. Perks come and go and can change at any time. Just ask someone who has owned since the '90s.
