I'm at my destination having done my first long trip yesterday. The chargers on the motorway all took contactless and were easy to use. I thought the big Gridserve at Southwaite had latched on to my car and wasn't going to let go, but realised I had been too slow and it thought it had a new customer hooked. I just offered it my card again then pressed "abort charge" and it let me go.
The Instavolts at Kirkby Lonsdale also took contactless. No problem with that, but paying for the parking (£1.40 but you get it refunded if you buy something from the Booth's shop) practically took a degree in logistics (and an elderly lady in a hurry telling me what to do).
When I got to my destination it was more fun. There are type 2 chargers right beside my friend's house (at a rip-off price, but it's only for a couple of days), but they don't take contactless. I couldn't see a way to get a card for them in advance, although they did keep demanding a card when I got there. However I had been able (with some difficulty) to download their app before I started my journey and I eventually got the app to make the charger work. I dread to think what it would have been like if I'd arrived there with no app, no usable card and no clue though. At one point I phoned the number on the charger and it was answered and the girl on the other end was helpful. (The main problem was that there was strong evening sun which prevented me seeing what was displayed on the screen of the charger.)
So I would advise looking at all the chargers you think you might need to use and see if they take contactless payment. If they don't, get either a card they will recognise or a phone app that will let you control charging and pay, and do it before you set out. Don't rely on being able to download an app right beside the charger when you need the charge, in darkness or in pouring rain or in such strong sun you can't see the screen. It might all work out but a bit of preparation can save on stress.
