My biggest tip for you, or anyone whois interested in traveling on a budget, would be to search for cheap accomodation. While it is nice to stay in a beautiful, big, expensive
hotel, it's important to think whether that's what you really need.
Maybe a small apartment or a hostel would be nice too. Saving money
on accomodation gives you the opportunity to spend it on local food
or tourist attractions. In my opinion, that's a better way to explore
the country, than sleeping in a big, fancy bed. Another way you could
save money is by using public transport instead of taxis.
