"small amount of giftage to bring there and back... "
I'll keep the list small, mister! ^_^
I won't. ^ _ ^
I like using a garment bag to handle most clothing stuff, although it's not quite as perfect since I can't stick my toilet bag into my carryon. I have a massive 40L backpack which I've used as a carryon, though I have to be careful not to stuff it too full or it won't fit into the size checkers.
Which reminds me - the rules for luggage on international flights can be very different than domestic. Triple check the websites and read the fine print.
As to giftage - buy a suitcase while you're there. Of course, that means having one less to take with you.
