lol welcome Ashley.
When my family and I first started going to disney we would go on line and make our "dream vacation". We would pick all the things we really wanted to do and try, places we wanted to eat and the hotel. then we would price it out.
After the sticker shock wore off we then would pick the "must do's" from the "if the budget allows".
These are the things we considered (and still do when planning most vacations)
1) since we generally traveled during the hot months, resorts were uber important to us. we are not the type to go to the parks from dawn to dusk commando style. so we loved to stay at the deluxes. that was always a big chunk of our budgets.
2) The people at Disney are smart cookies,
ever notice how every rides dumps you into a gift shop?? we knew that souvenirs could quickly kill the budget. With our kids, each kid got 1 souvenir. we made them wait until we hit every park in order to alleviate buyers remorse. (generally this ran us ~120 bucks)
3) we budgeted 100 per person per day for food. Now rarely, rarely did we spend that much. since you are on a quick service plan, I would at least budget for 2 sit down meal if you are going for a week.
4) we also budget 200 bucks for "incidentals". lol come one, you have to at least get some mickey bars or a dole whip.
I know it may seem like a lot but our philosophy on vacation is always better to have more than less. Disney is our weakness, lol while we try to rein in the kids "can I have"'s, I don't want to go on vacation and have to say no every single time.
happy planning.
