I used to like credit cards a lot for travelling, it was a guarantee to get money and pay bills even when other bank cards didn't work. I never used credit cards at home, only when abroad. As long as there is no monthly fee I have no problem with them. Charging a monthly fee for a card that is rarely used seems like a rip off to me. I remember the first time travelling abroad my grand parents gave me traveller cheques and told me I could use them anywhere, which was completely outdated nobody accepted them and I took them back home. After that I got a credit card as emergency from my parents. And now after using it for many years I am not sure anymore, during my last trip to Thailand I noticed that exchanging cash locally was getting much better exchange rates than the bank was giving me at ATMs or in restaurants. It seemed really wierd to pay a fee and get worse rates. I could have saved atleast 120 USD by using cash instead of a credit card. So at the moment credit cards seem the most convenient solution but not the cheapest.
