I'll be in Ireland for five days in September. The plan is to spend the first night in Dublin to catch up on sleep, then take a bus to Galway for two nights. From there, I'm thinking of spending the day making a loop back to Dublin through Ennis and Limerick. Is this too much for one day? Would it be better to pick either Ennis or Limerick to for a stop, and if so, which one? Thanks!
