I'm extremely happy that you will be visiting us soon.
In this case I recommend getting in touch with RyanAir directly, as they will be able to tell you exactly which travel documents you need for your trip. :) Have you reached out to them yet?
What are your plans for this upcoming family holiday? Is it your first time in Ireland? I would love to provide you with suggestions, ideas and tips!
Por último, si lo prefieres podemos continuar esta discusión en español. :)
