Have any of you purchased new ATV? I'm going to a Marriott as well and wondering if wireless connection will work between iPad and ATV operating on the hotels WiFi network? (I'm assuming that if the TV's had HDMI connections in 2008 they still do today so only concerned about my 2 devices working together).
This is usually a no-go -- not only are hotel wifi networks often slow and unreliable, but they may have firewalls or otherwise that will prevent your devices from seeing each other across the network. And, the biggest problem is that most hotel wifi (even when free) requires you to go to a log-in page where you accept terms and conditions and/or pay. The
TV has no way of showing you that page, so there is no way to connect the
TV to such a network (which is absurd, but such is the design choice Apple has made).
The best workaround in this situation is to plug your MacBook into the wired connection in the room and then have it create a wifi network and turn on Internet sharing. Then you can connect the iPad and
TV to the network created by the Mac, and it should be able to stream content between the two. However, this of course doesn't work if you want to travel without your Mac (or if, like me, you have a Windows computer for work that you are more likely to be traveling with; in theory Windows can do the same thing but in my experience it is very difficult to get a Windows computer-broadcasted wifi network working).
