Thanks for your message and great to see that you are helping your boyfriend and his friends to organise this very special trip. 🎣
There are indeed many great spots for fishing on the island of Ireland. Are they set on a specific region/part of the island or would they plan their itinerary entirely around where they can find the best spots?
The Fishing Ireland
page is a fantastic place to get started with your planning, and you will find recommendations based on level of experience, or what type of fishing they are interested in. They could hire a fishing charter boat or try their luck at one of the stocked lakes. Either of these options will have gear rental available, of course, and can also help with the type of licenses that are required.
With regards to the accommodation, they might want to look at some of the self-catering
options. On the bottom of this page that I have shared with you there is a map where you can find different types of accommodation. 🛏️
I hope that these ideas are a helpful starting point to lead your research in the right direction. Let me know if you have any questions.
Have a great weekend,
