It doesn't really matter. Just go somewhere you fancy. I went from Southampton to Blackpool, then to Denham and back to Southampton.
Blackpool was nice, went up the tower, had lunch and went to theme park to go on the Big One or is it the Pepsi Max? Denham was rubbish, had a cup of tea out of a vending machine and left. The idea of going to Denham is that I took someone who used to have a PPL and he used to fly from Denham.
Anyway, just make a day out of it, rather than flying 300nm for the sake of it.
