It's really great to see that you have joined all of us here on the Community.
I would like to suggest taking a look at our Study English in Ireland
article which has some insight on how to arrange this. I wanted to also check if the group you are referring to is looking to study an English program whilst in Ireland in December?
There is a lot of information on the Citizens Information website that could also prove helpful relation to education in Ireland
Lastly, there are a number of possible contacts for you to consider in regards to available English language courses
- perhaps it could be an idea to reach out directly to see if any arrangements can be made whilst in Dublin.
I'm not too familiar with what else may be available to you, however, perhaps some of our other members may be able to share their own suggestions with you.
All the best,
