A while back mrhub posted about using 3M contact strips to use on his tablet to stream. Using his method you would not have to transport a laptop.
I have used this idea with a cell phone twice. Once at BLT and there was an open channel on EoE. We had a Bay Lake view in addition to the Castle view. The 2nd time was at VGC before we got our "real" room.
You put two contact strips on the phone camera side and two on the window or the sliding door. We didn't have sound either time but the video was fine.
This is his post. Unfortunately, the photos no longer show up. http://www.eyesonears.com/topic/2133-resort-stream-with-apple-device/page__hl__mrhub#entry19789
