Most likely. Just drop by the DVC desk out front of the Grand Floridian Cafe and they will take you on a tour. We had to wait 20-30 mins for a free guide, but it was pretty quick.
"There's a phone in the bathroom!" I couldn't help being reminded of Brick being amazed at that (and so was I) in the TV show, the Middle. The DVC guide told me that the show was actually filmed in the VGF for that scene.
The DVC Guides have desks set up in the GV on the first floor, so you can always tour a GV, but some of the bedrooms have the furniture cleared out so they can put in their desks.
