Decide what you are willing and not willing to do.....be realistic. After moderate or deluxe....its hard to go back to value, but it can be done. We did on a recent last minute trip and it was fine. Staying off site is not ok for us, but we know that and deal with it.
Would you be willing to drive? Willing to adjust dates and take kids out of school for off season rates and
free dining? Willing to do all counter service meals. How many days are you willing to make the trip for? 5? 4? 7?
While lowering cost is one way to look at it, increasing the money you have available to use is another, more flexible plan. Think of ways you can increase the money you have available for the trip...again being reasonable on what you are and are not willing to do.
ideas:
Cut 20-30- or more dollars off your grocery bill each week. Eat meatless a couple meals, coupon more, eat the sales, avoid processed foods and snacks and soft drinks.
Brown Bag Lunches
Avoid all Restaurants
Get a part time job
Sell things you have no use for on Craigs list or E-bay
Don't exchange gifts for any occasion with your spouse.
Spend less on the kids for holidays
Buy only clothes you REALLY need. Consider co-sign stores.
Give up disposable whatever.....plates, napkins etc.
Now no one want to do all of these and maybe there are only one or two that would work for your family, but if its something you really want to make happen, you might be willing to do a few of these. Be sure that the whole family is on board for the things that effect everyone.
Travel is important to us and we are willing to make a lot of compromises in our life to be able to do that.
Good luck! We keep a picture of Micky on the Frig to remind us why there is no Soda in there
