For the hotel bathroom. Small places, multiple bathroom users...believe me, you will be glad to have it. I take a Bath and Bodyworks one as they are small!!
Pack one outfit per person in a different family member's suitcase. Then if someone's luggage gets lost, they'll have at least one other outfit.
We found it easiest to take gallon ziplock bags and place an entire outfit in each (underwear, socks, clothes, hair accessories, etc.). I looked a little OCD, but it saved an immeasurable amount of time and frustration. Each morning I just pulled out a baggie, and we were ready and set to go.
