As long as hotel wifi is not encrypted to block an extender, we can setup the Almond in Range Extender mode. However, please note that the authentication process could be done only on the client devices (Laptop, iPad, etc.,). Moreover, there are possibilities that on few cases each and every device has to be authenticated to get the internet access, in that case you may not be able to connect Roku to internet.
Hence, if you are connecting the Almond to a network which needs authentication only once using any client device (Laptop, iPad, etc.,) to get the internet access then you can connect the Roku to Almond's network with out any concerns.
