I always take ONE suitcase for FIVE of us girls on all of our travels. I keep it easy and basic.
KIDS
2 shoes for each (1 sandal, 1 sneaker)
1 outfit per day plus 1 extra (if we have laundry where we are I bring 1 outfit for two days)
2 bathing suits
20 underwear
Toothbrushes and one hair brush for everyone
10 diapers and buy more when we get there
ME
1 outfit each day (yep)..
3 shoes (sandal, workout, nicer)
2-3 bathing suits
2 workout outfits
1 toiletry bag
Plenty of room to spare 😉
