Well, we had a great time on our short honeymoon thanks - largely down to your recommendations.
Inis Mor was brilliant, worth it just for the fort; a day touring Connemara ending at Kylemore Abbey (beware the gardesn close for the winter); a day in Dublin (need I say more!?) and a day pottering around.
Brillianr fish restaurant to recommend - O'Brady's on the Pier at Bearna - one of the best we have eaten in, and we have eaten in quite a lot believe me.
Thanks to everyone for your help...
