I'll be in Ireland for the first week of June. I want to spend a day on the Aran Islands but I'm a little nervous about whether I'll have enough time to make it to the Aran Island Ferry shuttle in Galway by 9am (for the 10:30am ferry from Ros a' Mihl). So I'm nervous to book that ticket in-advance in case I miss it. Do the Ferrys and shuttles book up so that I would need to book in advance or can I 'wing it' on the day of?
Thanks!
