What TP model should I consider that is portable/battery powered that will allow me to connect to a hotel's wifi signal and share that signal via wifi to my other devices (phone, iPad, PC, Apple TV, etc)?  AC750 Wireless Travel Router appears to only be able to connect to the hotel's internet service is via ethernet. I will only have access to a wireless signal that doesn't have a password (open network) such as offered at Marriott.  Once on the wifi you open a browser, enter name and room number to validate use.
