ISO WFH base along Wales Coast Path+Scotland

My name is Tony, and I'm a 34 year old man from the USA. My wife is hiking the Wales Coast Path, and I'd like to be vaguely nearby to meet up with her from time to time. I work remotely for a North American energy sustainability company, where I fix and maintain computers. This does mean that I work based on Central Time, so it's about 3pm-11pm BST. This includes meetings and things, but never louder than a standard speaking voice (I don't suspect I'm a stereotypical loud American).
I'm hoping to base myself at key points along the Wales Coast Path starting July 26th (I'm still working out lodging details before I get my flight and finalize my plans) from south to north, before heading up to Scotland sometime in September to see the Isle of Sky and some more hikes in the Highlands.
I'm quiet, tidy, and somewhat introverted. I'm interested in travel, nature, photography, and good food. I don't smoke and I don't mind if others do.
All I really need is a desk to work at during that odd shift. My wife would intermittently (depending on the situation) stay with me as well, but mostly she's through-hiking.
