Visit attraction websites. Many attraction websites will have a visitor information page that explains the admission prices for adults, children and seniors over a certain age. Some websites will even have specials and promotions if you purchase tickets before hand so you can skip the lines at the door and save some money.
Check airline and hotel prices. Although prices for airline tickets and hotel rates fluctuate due to travel seasons and traveler demand, you can get a good approximation of how much your trip will cost by visiting a travel search engine like Hotwire, Travelocity and Priceline. Third-party search and booking sites will have promotions like Name Your Own Price and packaged travel and hotel deals.
Use a trip cost calculator to approximate how much money you will have to spend on gas if you drive to your vacation destination. The cost calculator takes into consideration the miles per gallon (mpg) of your car, the price of gas and the distance traveled.
Take into consideration the cost of food and souvenirs. If you are bringing your family, allocate a certain amount of money per day for food for the entire family. Multiply the amount per day by the number of days to figure out how much money you will need for food on your vacation.
