We've done a mix of sites so far. There is a back to basics site in Dyserth (North Wales) that we did two visits totalling 10 nights (a 3 and a 7), which is near where we had a static. Big tent, porta poti (because walking across a field in the middle of the night just isn't needed). Site was basic, and the showers were little metal huts. Water was hot.
We did five nights at Bala lake, with more planned for another site on opposite shore. Worlds apart from the Dyserth site - lovely shower and toilet block, big kitchen block, on site shop, and on the water's edge. Cost was double though
If we are staying a few days, then we get leccy hook up. Can do 3 days without leccy - mainly the fridge. Have the choice this year of the van for the odd night, or multiple days in the tent. I enjoy it as I can really relax. Still mixing it up though, hotels and going abroad.
We are doing 3 nights in the van at the end of March. It will be cold and windy so have opted not to take the tent. I have a big battery bank and solar to keep the fridge cool - will be needed for a 7 night tour in August.
Saving a small fortune compared to having a static caravan. They are £5k before you even go (ground rent and insurance), never mind buying one.
Even dabbled with bike packing this year. Enjoyed it despite us having rain each night - which meant the tent was packed wet each day.
