Hi Kim,
I'm sorry you haven't heard back. I wasn't able to verify if the hotel/caravan park was still in activity but the last online reviews I saw were from October 2022 (which could explain why you haven't gotten a response so far)
There are other campsites and RV parks around Dublin though, such as
Camac Valley. If all fails, you might be able to find RV stopovers on the
Total Camping Ireland website. One last option would be to sign up for the
Safe Nights Ireland network if you want to park your RV for the night around Dublin.
What have you got planned for the rest of your stay? Will you tour other parts of Ireland with your RV?
Cheers,
Antoine
