There is on street-parking around the park of STephen's Green where the tour departs from and there are two large car parks about 5 minutes walk from the departure point (Royal College of Surgeons / Stephen's Green Shopping Centre and Setanta Car Park)
I used the Q Parks car park at St Stephen's Green. You can get a better rate if you book online in advance, particularly for a full day's parking.
Not their own parking, but there are car parks nearby
I'm sorry I can't answer this, as we were on holiday and using public transport
No! You get on the tour at a bus stop in a square so no special parking for the tour. Have fun!
I am sure there is, but you would have to research it. We stayed out of town at the Dunboyne Castle. We rode a bus into Dublin for the day. In researching our trip to Ireland I read several statements saying not to drive in Dublin. I took their advice. The Viking Splash tour is great and enjoyable. I hope you are able to go.
