Hi Janne,
It sounds like a wonderful idea to bring some secondary students over to the island of Ireland to experience life and a possible exchange visit back to Denmark!
There are several websites for teachers and students looking to connect with other European schools, please have a look at this list for some inspiration.
LéargasEilirelandEf-IrelandWe hope that you manage to organise a trip, please feel free to contact all of the above to see if they can help or put you in touch with some schools directly. There may also be some of our members and industry partners who would have some additional suggestions.
Speak soon,
Martin
