I completely understand you'd like to know more about the impact of the current situation on your travel plans, especially since you will be travelling here by motorcycle with such a large group.
Because things are evolving on the island of Ireland, and new information and updates are coming in every day, it really is just a wait and see kind of situation right now. In this case, I recommend staying in touch with your tour operator, ferry company, and accommodation provider for more news. At this point, we really can't tell where things will be in the future, but I hope everything will work out for you and your travel companions. I also recommend keeping an eye on the Traveller Health page
for more useful information and resources.
I wish I could provide you with a more clear answer to your question, and I hope we get to welcome you to the island in the near future. In the meantime, the Community is always here if you need anything, so please don't hesitate to reach out.
