Shannon will be my base for three days (husband is working there - no choice!). I'd like to use a hackney service to some of the more 'local' places we're going: Dromoland Castle, Ballyhannon House, Craggaunowen, Bunratty and Lough Gur. Is there a hackney service anyone can recommend? Is there a reason I should stick with taxi's instead? I won't be driving.
