Hi Troilus,
We returned from PDC early hours of this morning. We had been for only a week but found it very quiet, we were there in May last year and although it was not hectic in 2009 it was busier than last week. Chatting to the barmen in Spenders on Tues night and in The Whale and Ale on Wed confirmed that it is quiet for the businesses too!
Our accommodation was so quiet and we were the only people in some of the restaurants / bars at times but it was still a restful and chilled holiday. I don't like hustle and bustle anyway so this is in no way a complaint!
My only complaint stood with the cloudy weather for the latter part of the week
