You'll have to compare the prices...
Is rack rate with
free dining at POR going to cost you less than renting points at BCV and paying for the
DDP?
Then, it will be a matter of deciding on dining vs. accommodations....
For me, I would rather stay in a nice room and maybe eat a few less meals than stay in a smaller room and eat WAY too much food

. We use our DVC to stay in 1BR's and we have opted to use TiW instead of the DDP.
BCV studio for $10/pt for 7 nights: $1070
6-day PH tickets from UCT: $1265.80
Dining Plan for 2 Adults and 2 Children: $1018.50
TOTAL: $3354.30
POR standard room for 7 nights with 6-day PH (assumes FD added): $2543.30
I cannot give you an honest opinion because I have never stayed at a moderate resort. Looking at these numbers, I would be hard-pressed to opt for the DVC lodging over the Free Dining promotion, *IF* we were going to buy the DDP. For my family, the savings would be even greater since we have a DD who will be 10 next year, thus increasing the value of the free dining plan. I love my DVC, but it is because I utilize the 1BR villas. In this scenario, I'm comparing a mod room to a studio. While there is certainly a difference, I cannot honestly say that I would find it worth $800.
Good luck!
