Great trip
"The Ardilaun is a comfortable dog friendly hotel in Galway city, good location if a bit away from the city centre. Dogs are allowed in the garden rooms but you have to contact the hotel to make the booking for these rooms. There is a charge but its reasonable enough (15 euro per dog per night)."
Greta hotel in Connemara
"Renvyle House Hotel is a really dog friendly hotel in Connemara. The hotel is set in a really lovely location, looking directly out at the Atlantic. Dogs are allowed in bedrooms and in some of the guest lounge areas. Not sure of official policy in terms of leaving them alone in bedrooms, but it seems to be common enough.. Three is a small additional charge of €6 per night per dog."
