I went to Norderney last weekend. No problem with a stay of less than 48 hours. The place was heaving – I would guess ca 100 aircraft parked.
This is why the Scilly Isles don’t need GA…
Admittedly April 2021 is not a representative month, with CV19 depressing normal airline traffic, but that is a lot of flights! A huge amount of ££££ being made on that run. Also at the Lands End airport.
