Hi, yes you do it, however the bigger the tour the longer it takes to load. This is a well discussed issue on this forum and the over whelming conclusion seems to be to break your tours down, say max 15 VT's in any one segment and then just link into a new segment for the next batch. Its not such a bad idea as you are unlikely to capture the viewer into all 43 panos in one viewing - its a long time.
I have done several tours with alot of panos. I have put a link below to one I did for a Country Club. I don't remember the count but I know it's 72 panos or more.
