thats is possible but it depends on how you set the tour up - so its at your end rather than the guys / girls putting the tour online.
have a peek at my site to see what ive got - not really ready for visitors yet but its there. Two things to consider.
1/ if you want more than one tour going up eventually then when you publish it make sure you click on the 'share partial resource player' in the 'general' section of the publish setting and
2/ when you publish the stuff it appears in a folder within a folder like
mytour folder which when you click has mytour folder in it
easier just to give them the second folder
hope this helps
