I’ve only ever been abroad once when I was a child and have managed to save enough to take
my family and I to the Canary Islands this year.
I am quite embarrassed to say that I have no idea how to travel with money 
do I take euros in cash, or use a prepaid travel money card? Do shops and restaurants in Gran Canaria widely take these prepaid cards? Will I be charged loads?! Do I need a mix of cash and card? HELP!
