One of the most frequent questions you ask me is how you save money while traveling because it is a matter of balancing some things and I assure you that you can save while you have fun.
Everything is in taking advantage of the moment I want to say easy, in the place that you are taking advantage of free sites and activities, eg museums, parks.
Be flexible with flight dates this helps you get tickets at best prices, depending on the season.
Come away from tourist streets, a good option to eat at street stalls, it is economical and watches where the locals eat while more people are the best places to eat.
Use the public transport watch how the locals move in the place you are if you take a taxi try to be shared.
If you go to sleep try to make it in hostels, guesthouse, these sites, despite being cheap, allow you to meet people, remember that a good trip also covers the people you meet.
