Some travel expenses are inevitable; Anyway, you probably will not get a free hotel room or discounted ticket to Sea World.
However, you can reduce your travel costs further - you just need to know the exact time to book your trip.
Whether your next vacation involves an airplane, train, car or cruise ship, take a look at this expert tip for your trip reservations.
Trip on Cruise: Book one year in advance
If you want to get the best price on a cruise ship, you need to do some planning.
"You can get a very good deal by ordering a year," said Carolyn Spencer Brown, chief editor of Cruise Critic.
This is true regardless of the time of year you plan to sail.
You will never steal, but chances are you will get your preferred room with good grades - which is important if you are traveling as a family.
Cruise lines also tend to be thrown out - such as spa packages, tour packages, beverage packages or free plane tickets - if you book well in advance, Brown said.
Savings from the original booking will vary depending on the voyage.
To get the best value, ask a travel agency specializing in cruises to help you book your trip.
"The service they provide at no cost is incredible," Brown said.
Last-Minute Cruise: 10 Days to 3 Months Booking in Front
Shipping lines usually require passengers who have booked in advance to make the final payment three months before departure, Brown said.
Thus, cabins tend to open at this time if people decide not to travel with their travel plans.
This is a good time to get a deal - if you do not choose the cabin you get.
"A very good price for a cruise ship would be about $ 125 per person per night," Brown said.
However, he has seen last-minute deals at rates as low as $ 30 per day.
You'll find great last-minute deals on cruises sailing to the Caribbean and Hawaii between Thanksgiving and Christmas - when fewer people travel.
Look for this deal to appear in late October, Brown said.
Keep in mind that booking last-minute flights to the port can be more expensive.
And last minute deals on cruises are not available until the last minute.
You need to order at least 10 days to two weeks before departure.
Trip on Domestic Flights: Books During Initial Booking Window
The best time, on average, to buy flight tickets for domestic flights is 54 days before departure, the CheapAir ticket search engine is found by analyzing 921 million airline tickets.
However, there is a main booking window when the lowest price falls between 21 days and 105 days before departure.
Rates can fluctuate a lot during this window, but this is the best time to find in-flight deals, according to the CheapAir's 2017 Annual Airfare Study.
Passengers will pay at least $ 20 to $ 50 more per ticket, on average, by ordering more than 105 days before the flight.
And if you order between 0 and 13 days before departure, you will pay about $ 150 more.
You can use CheapAir's When to Buy Flights tool to determine when cheap airline tickets are available for the flights you want to take.
Trip on Vacation Flights: Books August to October
CheapAir tracks daily fare for over 11,000 markets during the holiday season, and has found that the cheapest airline tickets for the Thanksgiving holiday are available in August and September, Klee said.
The cheapest flights to Christmas are found in September and early October.
However, the days that you choose to fly during the holidays also have a big impact on the price and how much earlier you have to order.
"If you are traveling on peak days - the Wednesday before and the week after Thanksgiving - not only if you expect to pay a hefty premium, but it is also more important to buy early because most of the flights will eventually be sold out," said Jeff Klee, CEO at CheapAir.
"On the other hand, if you are flexible with your travel dates, you could be better off waiting a little longer."
Trip on International Flights: Book Four Months or More In Front
When to book an international flight is highly dependent on your destination.
To get the best price on flights to Canada and Mexico, book 59 days in advance, according to CheapAir.
For flights to South America, the best price is available about 80 days before departure.
However, flights to Europe need to be booked 100 days in advance to get the lowest rates.
For Asian destinations, the best price is available 89 days before departure.
Flights to the Middle East are at least booked 120 days in advance.
And the best rates for the Caribbean are available at 77 days before departure, according to CheapAir.
Hotel Rooms: One Month Booking in advance
The best rates for hotel rooms can be found 31 days before your arrival, said Cheryl Rosner, CEO of boutique hotel bookings site Stayful.
This is true even for peak travel seasons and survives over the Thanksgiving and Christmas holidays.
If you do not tend to plan ahead of time, you're out of luck.
There is another window of opportunity to get a good seven to 11 days before the stay, he said.
The best way to get a hotel deal is to be flexible when visiting destinations, says Brian Ek, travel analyst for Priceline.
For example, a package that includes round-trip tickets from New York to Las Vegas and accommodation on Treasure Island is $ 470.00 per person from November 13-16, but only $ 350.00 from December 6 to 9.
Last-Minute Trip: Book Hotel Rooms at the Day of Your Stay
If you are willing to gamble about whether a room will be available, you can earn a lot by waiting to make a hotel reservation until the day you stay.
Last minute hotel savings can be up to 60 percent, Ek said. You can find this offer through last minute Priceline deals, Hotel Tonight feature and LastMinuteTravel site.
Be aware that the hotel will not start making cheap fares until 11 am local time, Ek said.
And the number of rooms they sell may be limited. "So, pick a destination, sync your watch and start counting down," he said.
