We use Command Strip hooks all over the place- from pictures to towel racks and more. All works well.
The only thing that does NOT work well for us is the Command Strip Velcro when it's on an interior wall. The walls have so much give, that you can't really push to make solid contact with the velcro. That stuff falls during travel pretty regularly.
Screws also work. We have a coat rack, a double towel bar hung, and a small fish bowl with screws. Just keep them short, use anchors, and you should be good.
