1derfultigger,
I have wondered about this myself and I go just about annually.
Disney changed their ticket pricing strategy a few years ago to now if you are in a park 3-4 days, it costs very little to get a 5th, 6th, 7th day etc. I've considered buying at the gate, buying in advance from wdw, buying from a discounter on-line, buying from the WDW center in Ocala on I-75, annual passes, the timeshare route, andonandonandonandonandonandon......

Then add on the water park option, park hopper, or unused day options, blah blah blah....
Last time around I hit on something that worked for me I think. I considered buying the 10 day (longest) pass on line in advance on wdw.com with unused day options; it works out to be cheap per day (I think I priced out the 7 day with unused as the cheapest per day) but I would have had to shell out a lot of money up front, hold on to the tickets for subsequent visits, etc...
So last time I just bought tickets in advance from wdw.com (at a slight discount) for the number of days I planned to be in the park for that visit. I planned to do only 1 water park so I didn't buy that option, didn't buy unused days, and we don't park hop as a general rule. Once you compare an on-line discounter and wdw.com advance purchase both on an after-tax basis there is very little difference.
My belief is that buying tickets as part of a package ceased to be cost-effective many years ago. We don't buy the
DDP either so I just book the campsite seperately, buy the admission tickets in advance seperately, eat one or two nice meals in the parks, once at HDDR or TE, and then the rest we eat in our pop-up or pack a picnic lunch to the parks (no glass or alchie allowed).
So depends on if you planned to want the DDP anyway, what kind of room/cabin you want, how many of you, how many park or h20 days you plan, and how much cash ya got on hand.

No simple answer.
Thanks for letting me vent - I feel your pain!
