Who are you flying with? Are you cabin bags or hold?
It makes a difference as if Ryan Air for example 6 and 4 year olds can have their own cabin cases.
My daughter and I have travelled abroad alone since she was 10 (now 16). Cheap flights, use the cabin sized suitcases and still take too much!
Me for 2 weeks - 3 swimsuits but they were chop and change, tankini, shorts, bikini bottoms, tank top.
2 throw over pool/beach tops
2 pairs shorts for pool
1 skirt for pool.
Vests for pool/beach
Evening tops 4
Light evening trousers 3
Light Evening skirts 1
Light evening dresses, never worn, got left behind.
This is wearing me out now 🤣
Basically a lot less than you'd think, especially if there's a laundrette on site and or you can rinse kids tshirts and have a clothes horse on balcony.
We've decided from now on we'll just buy towels at resort to save on space.
I'm stressing myself! Don't tell me you're going ski-ing!
I found when mine were younger - same swimwear and tshirts rinsed daily.
Evening wear, mix and match tshirts to 3 or 4 pairs of shorts. Little dresses x5.
And... I need a holiday.
