I'm amazed at some of the spelling and typos I see. Not that I've never made a spelling error or typo, but I do read each post before submitting it. I guess that's a waste of time to some...
Goodness, how big was your checked bag? And where your carry-ons 'legal sized carry-ons'? Not accusing, just asking...
and how old were the 3 kids? Little ones have little clothes, big kids have adult sized clothes. My DD15 is over 6' in her bare feet. Her clothes are cumbersome and take up a lot of room. As a matter of fact, they take up more room than mine. I'm only 5'8". Other DD12 is almost 5'5". Her clothes aren't tiny either. When we go, we usually go for well over a week and I do NOT do laundry while I am on vacation (barring an emergency). It is my vacation too and that includes the vacation from laundry. I can do that when I get home. We need at least 1 and 1/2 bags per person. We usually fill the other 1/2 up w/ souvies to bring home. During the summer, we will use at least 2 shirts per day as you get hot and sweaty and want something fresh after the afternoon break. During fall or winter, you need some of everything. One trip we even needed our winter coats and gloves in the evening (for CP) because it was cold (low 40's) and you were outside for a long time. I completely understand people pack differently. I would rather pack/take it, and not need it than to not have it available. But that is me and what works for me. This is also why we are flying w/ SW. It's all about choices.
