We're going to be in Dublin next weekend with 11-year-old DS and will have quite a bit of time to fill. I don't know very much about the city at all so I thought I'd ask the MN hive mind for ideas. We'll be staying in the centre and won't have a car. DS loves anything to do with cars/driving and will probably want a tram ride. DH wants to go to Dublinia and pop into the national museum to see a specific exhibit, but other than that we're fairly easy and it would be nice to find something exciting/memorable for DS to do.
