Hotel Wi-Fi is a great thing for travelers - see which hotels have the fastest Wi-Fi. You can connect your laptop, tablet or smartphone to the Internet and avoid using your expensive cellular data plan.
Of course, not everyone wants to use public Wi-Fi for sensitive surfing, and some hotels charge a pretty penny for the service. That's when you might consider turning your phone and its cellular connection into a Wi-Fi hotspot to power your Wi-Fi-only laptop or tablet instead. Or bringing your own standalone Wi-Fi hotspot that you've purchased from your cellular provider.
Unfortunately, that tactic doesn't sit well with some hotel chains. The American Hospitality & Lodging Association, with Marriott at the forefront, asked the FCC to let them block third-party Wi-Fi hotspots.
They claimed it interferes with the hotel Wi-Fi and can make it worse for other guests. When the FCC didn't go for it, Marriott decided to act anyway.
