Amsterdam Manor got electronic safes a few years ago so that has solved our problem since now we just create our own code for the safe. I would think more of the hotels would be getting the electronic safes when they do room upgrades, too. Seems like everywhere we travel in the U.S., the hotels all have electronic safes now.
We're looking at some of the PacSafe products for an upcoming trip to Paris this summer - the apt. we rented does not have a safe so we need to bring one of our own. http://www.pacsafe.com/www/index.php
