Have a lovely holiday Justjules, totally agree with the others, ironing is the last thing you should be stressing about. During the day, it's tee shirt/ shorts or swimwear so no need to iron as no one will notice . Linen is a waste of time ironing anyway, and you can get away with the " lived in look" 😄
Last time I went abroad was October, so when I washed the stuff in my return and ironed some of it, I put it all away together in spare room, as wouldn't be needing it again.This time round it was great as I just transferred it to suitcase.
