The main problem with hotel Wi-Fi is they don't want to spend the money to create decent Wi-Fi throughout, by 1) buying faster bandwidth like I have at home, and 2) they don't put enough antennas around the hallways. I can measure 25-30 Mbps outside one room, and two doors away either side, the bandwidth is 2-5 Mbps. I always seem to get the room with 2-5 Mbps!
Because of this, I usually cannot stream from home server, so I always travel with a wireless hard drive with music and movie files on it so we can enjoy listening to the BT speaker, or new Tap, or watch a movie on the iPads in the evening if we want to.
