Lots of good hints here, everyone, thanks...and thanks for that link to the "Travel Products" forum - never would have thought that's where packing hints would be, I did look around before posting this thread and no category jumped out at me.

We're going to dress nice on the plane which will take us through dinner, then wear the same pants the next 2 days with 2 different tops, then wear the first day's pants with a clean top to fly home. One sweater that I'll wear every day to keep warm.

We're going to do a trial packing in a couple of days (going in a week and a half).
