Way too many variables but I'll try.
We usually do three trips a year - about nine days over Christmas, about a week at spring break, and then one other long weekend - either for Food and Wine, between semesters in May, or between semesters in August. There are three of us - all adults since my 13 year old is an adult. We only
DDP on the Christmas trip. We cut costs by using our DVC points at times and we're AP holders (PAP holders this time around).
For spring break:
4/3 deal at POR with insurance and nine day tickets: about $2100
Food: I'll budget $100 a day for the six days we'll be on property. We arrive late on a Friday and will leave early the next Friday. That's about $600. That includes breakfast in the room, mostly QS, and two TS meals. We have the DDE/TTW for the two TS. Another $600. Note that we are cheap eaters as we don't drink soda or get a lot of dessert. No character meals anymore either. We have our favorite QS - Sunshine Seasons, Morocco, and Japan in Epcot. We also like the food courts at POP and POR. One meal is always a monorail progressive meal - hitting all three QS at the three monorail resorts.
Tickets: Our AP's will be up for renewal. We're upgrading to PAP's and we're FL residents. We'll turn in the 9 - days (after using them once to get full value) and the additional cost will be about $300 total - a little less probably. I have the exact numbers but not here.
Transportation: We drive from the Panhandle. $200 total including gas and a food stop each way in Tallahassee.
Dogs: A week of kenneling at our vet: $250.
Souvenirs and IKEA : $200 - most at IKEA which is my own little version of the happiest place on earth.
We'll get $200 back with the gift card.
Approximate total: $3600 but that includes the PAP's for a year.
Not too bad. The Christmas trip is always a DVC trip and with tickets paid for, it's a cheap one.
