Recommendations for camping and working (North West and slightly beyond)

Hello! I'm hoping to get away for a few days and I had the bright idea to go camping. But it's not going to be a full getaway as I'll be needing to work.

Does anyone have any tips for camping while working? All I need is wifi and power. But coffee and tea would be a bonus! I'll be taking a small tent, so looking at pretty basic pitches.

I'm based in Manchester and looking around the North West, West Yorkshire, North Wales. Specific campsite recommendations would be amazing. But perhaps I'm asking too much, and I'm better looking for coworking spaces in small towns and finding campsites relatively nearby? Cafes may be an option, but I've never felt comfortable working in them and ordering two hot drinks all day.

Cheers!
