Although I believe you will have to cross an actual (service) road, so the walk may not be desireable for those with children. (I think there was one dis poster that had a story about their child getting hit by traffic going to CR, although they mentioned Disney handled it well after the fact)
The walk is not bad at all.
You do cross a road but most WDW Staff is very cautious and careful. You of course must be careful, there are some people not paying as much attention as they should but not the norm.
There is a nice sidewalk that parallels the MK bus stops and it is fairly well shaded once you cross the road. The first park of the walk going toward MK is in the sun and through the Contemporary / BLT Parking Lots (not really pretty). Once you cross that road though you get the Disney Feel.
You could always just cross over to the Contemporary and take the monorail if concerned.
So are you guys figuring 10 minutes from the lobby of BLT to MK entrance? That is quick! That would be great and easy. I was trying to get a gauge by looking at some of the maps and aerial photos, but it was hard to tell how far away it was. So, is that about how long it will take to catch a resort bus? It has always been a pain to resort hop when taking Disney buses. I was wondering what the best way to get to AK or BC from BLT. Would walking to MK bus loop and catching a resort bus be the quickest and easiest? It just sounds too easy. In the past we sometimes would catch a taxi b/c resort to resort could take 1.5 to 2 hrs bus hopping.
To me real traffic takes me out of my complete escape into the fantasy Disney world and subjects me to too much of the real world, and that is not vacation to me.
