Bring your own personal travel Laundry Line and Sink Stopper Laundry Kit with you when you travel.  When staying in hotel rooms, there is no guarantee that the sink stopper will be working. Use the sink stopper while putting in your contacts, or to wash undergarments in the sink. 

The portable travel clothesline has loops on both ends that can stretch across the bathroom up to 7 feet and be attached to a shower head or towel rack. Loops around itself at one end and then use the included 2 ties and Velcro strap to secure it to itself at the other end around a towel rack, shower head or door knob.
