What to wear.
First of all, usually in March we travel with 4 suitcases...including carryons. The December trip it will probably be 6-7 suitcases(including carry ons).
I am packing the following:
3 Capris,2 Jeans,2 Knit pants(like dressy sweat pants), 3 LS Shirts, 4 SS Shirts, 2 sweaters,1 Knit Jacket,1 Jacket with removable lining, Hat and gloves, 2 bathing suits, 1 coverup, 2 pr shorts(if weather is going to be warm). One nicer outfit for Christmas.
For kids
2 pr unzip pants, 2 pr jeans, 2 pr athletic pants
3 ls shirts, 3 ss shirts, wind breaker, 2 sweatshirt,
kakhi jackets, and coat, hat and gloves, 2 bathing suits, and something to wear as a coverup. 1 nicer outfit for Christmas.
DH does what he wants.
I do laundry every 3 days, and will tweak packing list baised on weather forcast 2 days before trip.
I wear my bulkiest items on the plane...and those outfits are included in totals.
Hope this helps.
