I think it is a great idea to tour more than just your home resort and I am surprised that DVC does not encourage it. As we all know, your "HOME Resort" is not the only place you are at "HOME" in DVC. As a matter of fact we have never stayed ay our HOME resort yet! We bought at BWV because that is what was available, but we have never stayed there.
As was suggested here, definately go to the different resorts and walk around to get a feel for each place, and ask at the front desk to see a room or two. Go for it!
It is the best decision we ever made for our family and for my sanity.
