I have been to Oban and got a brilliant B & B from the tourist board - I always ring them and ask their advise. It is quite anumber of years ago and I can no longer remember the name of where we stayed, but it was a woman with children whose husband was a fisherman. We found them extremely friendly people in Oban - you should have a lovely time - if yuo give tourist board for Oban a ring they will run through the various prices/stars etc
