I am going to Majorca in September . Luckily, I don't live in the UK, so I am not subject to the Govt. stipulations. All we have to do in Jersey is to take a test on return arrival & keep , relatively, social distanced until we get the result (max. 2 days). I have no qualms about visiting Spain; if I have to I will self-isolate for 14 days when I return.
