I have seen in-room safes of all sizes, shapes, and appearances of "safety" or otherwise. The large ones big enough to hold laptops do exist! Since I often work out in hotel gyms, I often face the choice of using them or not. For whatever reason, I tend to trust the ones with electronic codes and I have never had anything go missing. However, once I had a problem reopening one (at a luxury property in Latin America) and was forced to ask the hotel staff to open it. They were able to do this with a master key, even though the battery in the electronic safe had died. The hotel manager simply pulled back a sticker on the outside of the safe to expose a keyhole. Now, I always keep an eye out for such stickers but have yet to see another similar safe in the US or Europe.
