I am not sure about Killaloe b&b's , the lakeside hotel would not be my cup of tea though. There is a really good b&b in Tuamgraney/Scariff area, I would recommend, AA approved too. It is approx 10 miles from Killaloe beautiful view from there up too.
Best option is to get to Killaloe early and go to ther tourist office -on the bridge at the clare side of the bridge-they will fix you up.
