As I mentioned, I have used it several times on cruises in the past. If memory serves, most if not all ship net services do require a two entry login. Either a cabin number or username and then a code, birth date, booking number, etc. to connect. So, I'd say the simple hotel logins should not be an issue. Great for sharing WiFi with travel companions at the dinner table or other meetings. We travel with other family at times and they are thrilled to be able deal with emails once or twice a day. Not to mention free WiFi calls to the US if their carrier has that feature like T-Mobile.
