Just read your post relating to Guernsey bmg buddy. Thought I would relate a story about my visit there !

In my working life (I retired 12 years ago) I used to visit a customer in Jersey once a year. Always an enjoyable visit, occasionally with an overnight.
(FAO mickd....I was a runner-well jogger in those days and it was always a treat to go for a run from my hotel in St Helier)

On this occasion I was planning to fly there (from B’ham) and return same day as I needed to be elsewhere the following day. Unfortunately my early morning flight to Jersey was diverted to Guernsey as Jersey was fog bound.

So we landed and awaited in their airport terminal. Time passed by and eventually there was an announcement that there would be a flight returning to B’ham shortly, but that would be the last one. Those passengers not wishing to take it would be put up in a hotel in Guersney and ‘island hopped’ to Jersey in the morning.

Sadly, owing to commitments the following day I took the flight home.

So I have been to Guernsey but spent all day in the airport terminal !

I understand that such a situation with one island being fog bound is not unusual ?
