The big point between mods like CSR and POFQ (refurbed rooms) vs value is bed size, as both these mods have queen beds, the other is a hot tub. We stayed at Pop in 2007 and loved the resort theming, pool, etc., felt the busses were fine. This past December we stayed at FQ, in a refurbed room, and the queen beds and extra space were certainly welcome. We did use the fridge (free in mods, charge in value), but not enough to make that worth it, and honestly, it was TOO cold even for the hot tub this time, but it sure did look inviting, and when it was warm, as the first trip, we would certainly have enjoyed it; it was something we commented on wishing we had that trip at the end of a long day in the parks. As noted, mods also have slides which values do not, most mods also have TS restaurants, though this is not a push to me, as we rarely eat at our resort.
OP, I would also mention that the only character meal that would be 2 credits off the top of my head is CRT, so not sure that you really need DxDDP to do some character meals. Our first trip we did Donald's Safari bfast, Ohana bfast,Crystal Palace, Garden Grill, Chef Mickeys and 1900 PF (Cindy, Prince and steps), all single credit meals. This past trip we also did Cape May breakfast, and we still haven't done Akershus or H&V, but these also are characters for one credit.
