When packing, set aside the pieces you intend to bring and ensure that they are clean and ready to be packed. Contact your travel agent about the hotel's in-room amenities - such as a hair dryer, an iron and board, soap, shampoo etc. - so you'll know what to leave behind.
Jewelry - don't take what you don't want to lose, and leave behind the flashy pieces that could attract thieves. Keep makeup to a minimum to save space, and leave the perfume behind when scented lotions will work just as well.
