You won't get a hotel nearby, closest is probably the Rathkeale House Hotel about 25 mins away. Askeaton or Foynes are both less than 10 minutes drive so would be closer but there's no hotel in either place but there are guest houses/B&Bs.
How early is early? Limerick city would be no more 45 mins drive to Aughinish and if it's ealry morning then maybe could be done in slightly over the half hour.
Foynes would probably be the closest town with Askeaton next not sure about B&Bs in either but as both have International Industries nearby I'd guess there must be some decent B&Bs is both.
