I think "VR tourism" could be a pretty cool thing if large scale 3D mapping of interesting places takes off. I imagine it to be a little like a more immersive "Street View" from Google Maps.
You could walk through all of the strange passages of the pyramids one minute and then be looking at Earth from the surface of the moon the next.
To be honest, Google Street Maps and Google Earth already do this for me. There are a lot of places that I've wanted to visit, but after seeing them on Google Earth I've found that my desire to visit such places is gone. I look at it as a cheap form of tourism without the risk of pick-pockets ;-)
However, I still want to travel and experience places that are not man-made. I love to hike and there are trails all over the world I'd like to explore.
