My daughter, a friend and I are doing a whirlwind university tour of Iceland and Ireland in January. The girls really want to study abroad, preferably in Iceland, so we're flying there first, spending Saturday morning through Wednesday morning in Reykjavik and then flying to Dublin until Sunday morning. We hope to visit the University of Iceland and the Iceland Academy of the Arts, and then Griffih, UCD and Trinity in Dublin. BUT we also want to cram as much sightseeing and nightlife as we can in the days/nights. After reading various posts, I'm leaning towards not renting a car in Reykjavik and doing a couple of the adventure excursions - Northern Lights? Golden Circle? Any suggestions/recommendations - we have little money and I know Iceland is expensive. And Dublin, where to begin? time for a day trip outside the city, I hope? INput appreciated!
