Thanks fred but I'm pretty sure it would still be a 10 day quarantine.
Flights - That's what we've done with KLM over the last decade; at the moment KLM are asking $2300pp and it seems they've suspended their City Hopper from Amsterdam to CWL until August. Also, having a stop-over in Europe would also initiate the 10 days as the EU are sticking with the Schengen Agreement. We're booked with Icelandair, short stopover in Reykjavik but the island is on UK's Green list. Car rental is also a nightmare with costs in crazyworld as the providers cut their fleets during the pandemic.
