The other (global) issue nowadays is that most hotel Wifis are totally congested during rush hours, which is owed to cheap home-grade Wifi equipment, the lack of any traffic shaping and insufficient uplink capacity. Interestingly often it is not even the data volume that stresses infrastructure but the mere number of Wifi clients connected, as most Wifi APs start breaking down once more than 20 clients come online. A number easily reached now that people take 2-3 devices along.
Configuring Wifi channels properly (either exactly overlapping so Collision Avoidance does work or at least 4, better 5 channels apart to evade overlapping) and rolling out 5GHz coverage could mitigate one of the bottlenecks.
That said, even if your hotel offers Wifi you can hardly rely on it these days. Cellular service is also much more secure by the way as - in contrast to Wifi hotspots - all data is being transmitted encrypted over the air interface.
