Most likely, given it's a hotel and they are notoriously cheap when it comes to infrastructure, they have the bare minimum of WiFi access points and coverage. Thus, the phone is probably cranking up the transmit power to maintain it's connection. This will dramatically
shorten the battery life, and also tends to make the phone get rather warm. I've had this numerous times in hotels, and it can kill the battery in as little as an hour (usually more like two). And on the laptop, the signal strength will also be very poor and experience frequent disconnects.
If the hotel offers a wired connection, I always use that. I have a little pocket D-Link wireless travel router that I carry around and hook up to the hotel's Ethernet. I then use my laptop to sign in via my private WPA-passworded SSID, after which any of my WiFi devices (e.g., the 8320) are able to connect and get service and I don't have to worry about poor signal strength as the AP is now right in my own room.
