I went to Oban for the first time on Saturday with Mrs PhilD (from Blackbushe) and can certainly endorse the above comments. First of all Prestwick were very helpful - I got an IFR transit as I was in IMC through most of their zone.
We were made to feel really welcome at Oban with coffee and biscuits. Brian was doing the airfield duty as Paul was out watching the procession at Silverstone. It's a really pretty location, especially for us southerners used to the flatlands down here, where 400ft hills constitute a major obstacle.
Based on the recommendation from 2D we had booked the Lerags House hotel. This was a great decision as we had a real 'home from home' welcome from Charlie and Bella (and Fingal), and great food. It's a bit of a cab ride from EGEO (30mins/£20), but well worth the trip.
Finally we had a very useful 30kt+ tailwind on the way back, with over 170kts groundspeed much of the way.
All in all a great weekend. We hope to be back at the airfield and hotel soon.
