Coastal locations are excellent for Nav. - half blue, half brown helps beat initial nerves!
I agree with L'aviateur; in theory absolutely correct.
Best results? You can only get this from the FTO. The CAA will not confirm or deny figures - 'commercially sensitive'. A painfully inadequate position for an entity which should be promoting public reassurance through transparency and service.
Best reviews? You can only get these from the FTO. The best way is word of mouth from someone who has been there. Look him/her in the eye as they answer and make your own judgement.
Fewest distractions? Most FTOs have their accommodation well away from the fleshpots - keeps the costs down.
