I used it a few weeks ago and was superb. My family were over in Ayrshire during the holidays and I went over on the Saturday morning at 7am from Campbeltown and thought it was fantastic. So relaxing. Got on, had breakfast, went for a sleep and woke up at Brodick! Enjoyed the 1 hour crossing from there to Ardrossan on the open deck.
The following day we returned to Campbeltown with the family (and car) and it was simply the most relaxing, fantastic way to travel to Campbeltown. No stress, weather was stunning, family loved it and was a really great way to end their holiday.
The Sunday we returned there were over 240 passengers and apparently more returned on the sailing back to Ardrossan - it certainly was a busy place when we arrived.
Anyone I have spoke to says it is great - especially visitors to the town. More consideration on the timetable is probably required but as it is the 1st year then the important thing is to build in year 2 and 3 to make the pilot a success.
I know I will use it more often if the timings suit.
To even up things I used to 6.30am bus on Wednesday morning and was really surprised how busy it was from Campbeltown - by the time we reached Lochgilphead there were only a couple of seats left. Same on the way home at 2pm on the Thursday afternoon - only a couple of empty seast leaving Glasgow so good to see

All modes of transport are vital to Campbeltown.
