If you need a hotel in less than a week, you can use the app HotelTonight to get amazing deals, consumer and money-saving expert Andrea Woroch tells Bustle. You just enter the kind of hotel you want, and the app will find you one at up to 70 percent off. There's just one catch: You won't know exactly where you're staying until after you've booked it, or else they'd have to advertise the discounted price to the public. But at least you can specify how nice a place you want.

Or, if you want to book in advance, a great way to pay less than the hotel normally offers is to go to RoomerTravel.com, says Woroch. If people have a change of plan and can't stay in their hotel rooms, they post them there, and you can book it at a huge discount. A quick search through the site tells me a lot of the rooms are around half off.

Expert tip: When you're Yelping restaurants, set the filter to include places with deals, says Woroch. That way, you can save money eating out while still getting the best possible taste of the place's culture.

If you plan to go to a club, zoo, theme park, or anything else that requires tickets, you'll pay less by buying them online than you will once you get there — even if you're buying them from your phone on the way there, says Woroch.

If you search for hotels or flights to one particular destination a lot, advertisers' algorithms will pick up on how interested you are and up the prices, Jennifer McDermott, Consumer Advocate at finder.com, tells Bustle. To avoid this trap, always search in incognito mode.

"Most people book their travel later in the week, so airlines tend to release deals Monday evenings to even out their lull," McDermott says. "Once one airline releases a great deal, competitors tend to race to match it, and so the best fares are often all out on a Tuesday afternoon." That said, the best deal may require a zillion transfers, so just go with the best deal that won't drive you up the wall.

There's something to be said for going to Ibiza in the summer or Vermont in the winter, but the upside to traveling off-season is that it's much cheaper, says McDermott. Plus, you might discover lesser-known attractions and get to know the locals when there aren't so many tourists around.

Aside from being cheaper in general, the cool thing about Airbnb is that the prices are more negotiable than hotels. If you're staying for a long time, the host will often offer the room to you for a lower price. And if it's last-minute, they'll likely give you a discount because they just want to rent out the place, travel writer Angela Karl tells Bustle.

It may seem old-fashioned, but travel agencies offer package deals on flights and hotels that are often much cheaper than you'd get by paying for them separately. Plus, they'll do the planning for you and have great recommendations, since they do this every day.

The site Workaway lets you find free places to stay in exchange for helping out there, Jennifer Kanikula, writer for The SoFull Traveler, tells Bustle. You can stay with a family in Bogota by helping out on their farm, stay at a Costa Rica hostel for free by volunteering there, and stay in the desert in Israel while caring for the horses. Of course, this wouldn't be ideal if you want lots of time to yourself to work or explore the city, but it would be a great way to meet new people.
