The Killyhevlin is located just outside Enniskillen, and has both individual rooms and lakeside lodges.
Belmore Court is located in Enniskillen (within walking distance from the pubs!) and has a variety of rooms available.
When booking with either of these hotels, if you say you are part of the O’Riordan/ Blackwell-Smyth wedding they should offer a preferential rate.
