Just that really, do you have a preferred use of passport, combination of passports?
We've only done it as a family once since Brexit and left you on our EU passes and entered UK on our UK ones, leaving UK there was no UK check, and we were waved through with our EU ones once we hit NL.
This did mean I had 10 passports on me for the duration of our trip which is not ideal. Currently in France and we can all travel on our ID cards which is bliss!
Just wondering what other people do and how it's easiest / quickest etc.
Obviously depends on mode of transport, and we're fortunate enough that the DCs are old enough to use the automatic gates if we fly (very rare these days)
