I use Plugshare of ZapMap to figure out where I might need to charge (assuming Superchargers not available). For example, during a weekend stop in York I figured I would need some top-up ... plenty of charging points of course, but driving X-Miles to one, to then slow-ish charge would be an annoyance, so I looked for one in walking distance to hotel and then at car parks that we might use. (I've also used at Park & Ride on other occasions). Also need fallbacks in case occupied or bust - they don't have anything like the reliability of Supercharger stalls.
Also worth looking for 13 AMP - I asked the hotel if they had external 13 AMP, "nope", fair enough ... only ... when we got there they did indeed have one, on a wall on a circuit that fed their advertising hoarding ... 13 AMP will give you about 5 MPH, so over a weekend you'd be fully charged.
So having found suitable provider then consider how you will pay. I haven't found a single one where you can just stuff a credit-card in and pay-as-you-go. I have no idea why every vendor wants you to use their APP etc. - and sometimes even have to deposit money with them beforehand.
I download the APP before I go (high probability that may not be possible sat at the pump
) and authorise a card if that is an option (without making a deposit). Then i make a deposit whilst at the pump, if that's the only way to pay. CYC seems best (so far) in that they require card registration but no deposit, and then they debit the card monthly for any actual usage. In Scotland CYC is free, and CYC seem to have reciprocal deals with a number of providers which reduces the number of APPs you might need. But their APP has no idea where their pumps are ... so use PlugShare of ZapMap to find them. In York parked next to three adjacent pumps and the CYC app claimed that two of them were over two miles away in opposite directions! (Which is then a bit of a snag trying to figure out WHICH pump is the one you are actually connected to!)
I phoned CYC Support to ask what would happen if I couldn't get the APP to respond when at the pump, and they said to phone them and they would initiate charge etc. which sounded reassuring. If you are going to use a particular "brand" often then worth getting an RFID tag (more money ...) so that you can just swipe that instead of using APP (and requiring internet connection / possible delay)
I've had some points take several minutes (5 probably ...) to actually connect, and same again to disconnect. I'd be charged in that time at a Supercharger! You may also find that the 13AMP at a Type-2 [dual] charging station is free. I've plugged in for 24 hours in a multi-storey like that before ... the Type-2 alongside has a separate parking bay, so I doubt I was hogging the 13AMP from anyone else, even for a couple of hours shopping trip it probably wasn't going to make any tangible difference to anyone, but I leave my mobile number on the dash in case anyone is desperate.
I suggest you go armed with 13AMP (i.e. the UMC cable) and Type-2 cable (comes with new cars, didn't when I bought mine). I also have a long extension with seriously over-rated (ie. fat) cable [when combined with UMC overall length needs considering] for when staying with friends - their frayed lawnmower cable is probably not a good substitute! Check that the cable/plug is not warm after an hour or so, and before leaving it on overnight.
Worth considering a CHAdeMO adaptor, that will give you about 50% of Supercharger speed, which is a fair bit better than Type-2. Unlike Supercharger, which charges faster from, say, 10%-70% or 80%, CHAdeMO charges better when SoC higher - so worth charging on Outbound trip by CHAdeMO as against Return trip on Supercharger.
