tinnub, PM'd you ...
ORDNorth,
The Westin in Dublin is certainly a great place to base yourself, particularly if you have not been to Ireland before ... search the Starwood forum for great info on this hotel.
You could even do without a car for many days, if based here. There is much to do in and around Dublin - Guinness Brewery

, Trinity College, Malahine Castle, Historic Tours of Dublin in DD Bus, novel Amphibious Tour of Dublin including trip down the Liffey in a WW2 vehicle

^ , Galleries, etc. etc.
Much to do ... to much to detail here.
Let me know if you have further thoughts.
Regards,
John P .
