I overpacked for sure. I took four outfits and used two not including jammies (sports bras are a WONDERFUL thing), three books didn't read any of them, Gas X (didn't work), six magazines, (read them on the plane and left them in the lobby at the hotel) shampoo and conditioner, (ended up using the hotel's 'cause I didn't feel like getting my own -- lazy, huh!) blowdryer (ended up using hotel's) lotion (ended up using hotel's) two pair of shoes, (ended up using my slippers) and bought some Croc's at the Denver airport -- who knew they were THAT comfy?! Water (three bottles -- security confiscated it) and make up (never applied once).
I could have made it on two comfy outfits, toothbrush, mouthwash, chapstick, facewash and moisturizer (don't like soap), one razor (not three), jammies, pair of crocs, gas reliever of some form, hairbrush, sports bras, and slippers for OCC.
Long story short, imho you really only need the minimum, less to lug around.
