OK we went for the first time first week in December 2012- we stayed offsite at Super 8 for $30ish a night- this year (our 2nd trip ever) First week in December 2013- we stayed onsite at POP Century (12days we were there) the cost was average $140/night- we did the
DDP and a lot of character dining, photopass+ also.
Not to be flamed but we had a HORRIBLE experience at our resort! We had mold in our room (a lot of it) Called on the phone and all they did was bleach the spot- still was there though! Housekeeping was HORRIBLE, they never took our garbage out for 4 days- beds were never made- top sheet blanket was bunched in a ball either thrown on bed or the floor- weird dirty towels on bed that we did not use (like they brought them into our room and left them on bed?) then they decided to take the bunched up blanket and we only ended up with two thin sheets for the rest of our stay!
So for me if we ever go back- I would stay at the $30/night and rent a car- and save the money- because we got better room service and also was treated better at the Super 8 then at POP Century!
But the plus side at staying at Resort- I really enjoyed just hopping on a bus and getting to the Parks- but that benefit- still does not out way the horrible experience we got and we were ignored!
DDP- you could take it or leave it- we did do a lot of character Dining- but the DDP- is a lot of food- if we do decide to go back- we will probably not want to do the DDP- we will probably just pre buy gift cards or put it on a credit card at the time of dining- we did not save money on the DDP- but it was nice and convenient just to touch our magic bands to their scanner and it be deducted off our meal plan- but again- we would of saved money on not doing the DDP.
It is up to you to decide what works best for your family- we decided to go "all out" and stay onsite, DDP, PP+- we had some great experience- but the resort stay was one of the worse experiences we have EVER encountered!
It just might of been a fluke - but when paying $110 more per night- it was really disappointing! We could of saved- $1210 just on that!
Also if staying the first week in December- it is pretty light crowds with most walk on rides, but some might be a 20-40 minute wait. Plus if staying onsite that week usually has POP WARNER- cheer and football kids age from 7-12? staying onsite- which could put a stress on some people- that really didn't bother us at all- other than they were cheering up and down the parks- which was just annoying- but not a big deal.
Sorry for long post. I do hope you enjoy what ever you decide- this was just our experience with staying onsite verses staying offsite and the same time of year.
