We've always done the DDP (free, every time!), and we've stayed at Pop and POR. It's always worked out a better deal for us (fam of 4-kids ages 11 and 6). And we're pretty laid back about it. We don't stress over who eats what, how much, etc. My kids aren't huge eaters, and my DH and I certainly aren't going to eat all that food in the September blast-furnace that is Orlando lol. So, for CS meals we usually order 2-3, and split them, and often have food leftover. At Yak & Yeti (CS), we order two and always have too much! And at the end of our stay, we ALWAYS have CS and Snack credits leftover--just because it's free doesn't mean we have to use it all!
Anyway, I think my point is that you really should sit down and map it all out to get the best bang for your buck. Are you paying for the DDP, or getting it free? Staying value, mod, or deluxe? Is your party mostly adults? Do you love character meals, buffets, TS? A lot of factors, but the point is that you have to know how it works best for your fam

. As for us, as long as WDW keeps offering it for free, we'll do the DDP and stay at our beloved POR!
