Don't miss on this. It is a fantastic way to get an idea of city culture, major attractions, or places to dine etc. These walking tours are without a fixed price, which offer participants an overview of the city. Most guides will subtly or not-so-subtly mention throughout the tour that they are doing this on a voluntary basis, and that tipping is the right thing to do. It is up to you whether you want to pay or not; I used to pay 5 Euros at the end if I like it.
Companies like SANDEMANs do such tours and you can find guides with umbrellas at major attractions of the city or you can get information on timings etc. through their portals.
Hostels, Airbnb and Couchsurfing
Most money spent in a trip is on accommodations. Hotels may be expensive but there are different alternatives available in Europe which may lead you to spend less.
I specifically admire the hostel culture in Europe. These are youth kind of hostels where you find dynamic and vibrant atmosphere. In a room, there can be several bunk beds - number may reach till 25. Pros are that you pay only for a bed and meet similar mindset people coming from different regions.
Airbnb offers homes away from home and through Couchsurfing you can approach locals living in city if they can adjust you for free in return of travel experiences you share.
Every wonderful new country you see is another time you have to move your belongings around, so carefully consider what you really need and cut out the rest to save yourself the hassle.
Don't forget to carry Travel plug Adapter. Your parents may fill your luggage with multiple food items but there is no need as everything is easily available through several Hyper stores, and Asian shops all around in major cities.
The euro (€) is the official currency of 19 out of 28 EU member countries and is widely accepted. These countries are collectively known as the Eurozone.
But other Nine countries (Bulgaria, Croatia, Czech Republic, Denmark, Hungary, Poland, Romania, Sweden, and the United Kingdom) are EU members but do not use the euro. Like Croatia uses Kuna , Hungary - Forint etc. You may get exchanged currency at few restaurants or hotels where they accept Euros. I used to get local currencies by using my Debit card (Thomas Cook) but never withdraw in excess as you may end up with few notes which is unacceptable in other countries.
Travel but be Alert
