I would have thought there were even more than that there. I know when I leave on Sunday I know I did not see everything. Too much to see and do in just two days. I really wish you would expand to three days. Even then it would be tough to see it all.
No idea how many blanks or other stuff is there all I can say is that its a TON. You cannot see it all in just two days but you can try. I do.
