We will be a group of 13 (8 adults and 4 children aged 21-8) traveling to Ireland in June 2014.We have family in Donegal and Sligo we will visit, but plan on sightseeing before and after. Currently we plan on flying into Shannon, and visiting the Cliffs of Moher the first day. Then on to Doolin Cave, Klyemore Abbey the next day. We'd like to spend a night and day on Clare Island, then on to Sligo and Donegal. We'd like to visit Giant's Causeway and Dublin. Ten of us will be going on to London for another week. We are debating between hiring a driver or getting 2 vans and car and doing the driving ourselves.The first quote I got for a driver was double what it would be for us to do the driving ourselves For most of the group, this will be their first time in Ireland. Any suggestions and do I have any glaring omissions?
