I have an annual policy so I'm insured without really thinking about it.
I have lots of weekends away with a group of friends, almost always in Europe.
I have realised only about half take insurance for these trips, with the others believing it's not needed for these short trips, they'll take the hit on any cancellation/ lost luggage and rely on GHIC for anything medical that can't wait until they get home.
I don't love this as I fear it will be me trying to get their bodies repatriated!
I was talking to a colleague who is very well travelled and she agreed it's not necessary for European travel...
