When I was there (inis mor) 3 of the 5 bars where open. we stayed in the only hotel which isn't that old. it was great craic and the group stayed together all night, a few of the lads had guitars and we attracted quite a group by the end of the night. there was a good crowd around and plenty of pretty ladies to look at, and that was november! book early for summer, i'd say it gets very busy.
