Can anyone recommend transfer to Corralejo in December ?
I'd give sun transfer a miss, terrible, using hoppa at moment cheap and reliable if a little slow.
The cheapest Hoppa option can give you a tour of most of Corralejo before setting you down.
These days I use their "max 4 stops" option which sometimes is a quick as a taxi transfer.
I use Viva transfers, very reliable just a little expensive.
