Thanks for the advice.
I've let my insurance know and they've said i'm covered withing my 90 days european cover. I'm going to buy a standalone RAC European cover also just in case. My dad is coming with me on his new Triumph XC so i've advised him to buy the same.

We will be doing the Holyhead to Dublin crossing then turning left down to camp in Wexford the first night then on from there. Riding the Atlantic coast sounds good then a finish in Dublin for a night before coming back. I just want to go but need to plan properly.
