The first thing you need of course is a daily budget. You want to decide exactly how much you’re going to spend every day for such things as gas if you are driving, hotel, tipping, taxi fare if you are not driving, meals, and spending money. Once you figure out how much you want to spend every day try to stick to it. If you spend a little less one day and you will have a little bit more to spend the next day.
Plan to travel off season. If you plan a vacation during the summer, budget family travel will be a lot harder to accomplish. What you want to do is try to plan your vacation at a time when the kids are normally in school. This is when you will usually find the best deals including excellent package deals and hotel discounts. Airfare will most likely be cheaper as well.
If you are planning to vacation in an area where there are theme parks which you want to visit, consider purchasing an annual pass instead of daily tickets. Usually these passes are about the equivalent of a couple of days worth of tickets. So if you’re going to be there for more than two days an annual pass is usually the least expensive route.
Consider renting an apartment or condo if you plan to stay for an extended period. A month-long stay in a hotel will be quite a bit more expensive than renting an apartment, so your savings will be substantial.
