Clarity
I don't think I can add anything new to the advice. I could get by with what I pack in a carry on and a second personal bag if I had to. I carry my golf clubs to I pack my clothes around the clubs. As others have suggested toiletries, etc... can all be purchesed at Mega-Mart unless you have some unique special creams, lotions, shampos. I wash out clothes and hang them to dry for use again. I take shirts, shorts that can be mixed & matched.
My wife on the other hand used to take two suitcases and still not have enough room. She is down to one large one, one carry on and one personal bag. I pack a second fold up carry on type bag that we use to help bring home the carvings, art, etc.. we buy there.

Good Luck
I wish I could be there with all of you this month.
