The channel islands are probably my favorite UK destination (or one of). ATC is no problem at all, I wish all controlled airspace was as easy to navigate (though the "not above 1000" out of Alderney has occasionally got the arse twitching
But they do allow a climb as soon as possible)...
All the islands are very good value for money, sensible landing fees, duty free's
and nice people, and 168hrs free parking at Jersey......you can't beat it!
