Travel to Greece on UK or Irish passports?

[MegCleary]

I have Irish passport, DH UK one. Our girls have both. Which would be best for them to travel to Greece and back on?

Bump

The Irish one.

DH and the DCs have British and EU passports and I have a UK one
We usually all travel on the British ones as we don’t mind getting them stamped and can’t use the gates anyway. Unless of course we discover one of the British ones has expired as we check in online 2 days before travel - we too the expired one as well as we did get some questions on the way into Spain and also on arrival back here

Irish of course, why would you not use your EU passports travelling to a EU country. If 3/4 have Irish passports and your DCs are children your DH would probably get away with going through in the same line as you as a family.
