First, I had two plastic containers that fit side by side in the bag:
Now, one of the containers, I use every day. It sits on my "vanity" shelf in my closet and holds my make-up and such. I added my contacts/glasses to it. Than in the other one I put things like our deoderant, medication, shaving stuff and so on. This keeps all of those little things together. When we got to the hotel, I just pulled out the containers and placed them on the sink; everything stayed together so it made packing to go home easier as well.
Than, I used the space left around the sides and top to add those things that don't fit in the containers:
Things like my body spray, hair gel and body wash fit along the side, shampoo and hairspray slide down along the front (not visable in the picture) leaving room on top for hair burshes. The only thing that I don't fit in this bag now is my hairdryer (yes, most hotels have one which works for most people but, due to my curls, I must use a diffuser which only fits my hairdryer!) My hairdryer fits nicely into our suitcase :-)
What a differance taking time to pack neatly did for us this weekend. This bag hooks over the handle of it's matching suitcase, which than rolls making transporting very easy. My husband thanked me several times for taking the time to do this - he commented on how nice it was to not have to carry all of that stuff!!
