One should refrain from planninga trip abroad during the holiday season, world tournaments, etc. as these are when prices hike due to a massive influx of tourists.
Book flights in advance
If you book flights at least 3-4 months in advance, you may get them at a relatively lower cost. You should also use multiple search engines to compare airfare, to save more.
Choose hostels over hotels
To avoid splurging look up some awesome hostels instead of booking a fancy hotel. Hostels offer free breakfasts and an opportunity to connect with other travelers.
Walk instead of hiring cabs
Book a free walking tour around the city you are visiting at your preferred time. This can also get you access tolocal guides who can offer you thebest recommendations.
Cook your own meals
Try to shop for some basic stuff from a supermarket and cook your meals as much as possible. You can also search for nearby street-side vendors who offer food at reasonable prices.
