I agree that Oban and Mull are two of the best locations going and I hope that (despite this bogging weather) everyone makes them 'must-do' destinations for their yearly Scottish trip
With PPR and fuel, I would always phone TLC in advance - a word of caution - I would not rely on asking ATC at Oban to contact them.
On several occasions, presumably as time fast approaches the bewitching hour of 5pm, Oban ATC have been asked (via Scottish ATC) if they can contact TLC to see if the refueller is available .... but strangely no message has been passed on. (I have personally experienced it once).
I would like to think that these are just isolated events and not some official wheeze .... not very professional if it is.
Come on now lads .. pull together ...
