We recently switched to Macbooks and tried use our old router, a DLink, at CBR in June. Both of my BIL's worked at it off and on for a couple of days and couldn't get it to work. We're thinking about buying an Airport Express to use just for travel. If we stay at higher end hotels, they usually only have ethernet cords. Which is fine if one of us sits at the desk, but since we both have laptops, it is a bit limiting and time consuming for us each to switch off using the ethernet.
