Hi Louise,
It's great that you are coming to Ireland very soon!
If you are under 25, the rental company may require years of driving experience or charge a young driver fee, as you may have noticed. We actually have a whole discussion on this topic already, especially helpful for younger drivers. You can check it out
here. 😊
If you end up not renting a vehicle, you can still use
public transportation and visit offbeat locations (depending on bus services). You could also join an organized day trip through local
tours-operators if you'd like. What did you have in mind during these 4 days with us?
Have a wonderful trip ahead!
Antoine
