When traveling, use a pillow case for packable dirty-laundry bag. Keep luggage organized, put socks & undies together. Wrap breakable souvenirs. See comments for travel packing ideas. Lost a charger, check for a loaner from lost & found at hotel. They should be able to loan you one others have left behind. Use zip lock bags to "vacuum pack" anything bulky. Stuff the bag full, zip it part way and sit on it while you finish zipping!
