I suggest you download and try it.
Be mindful also of the URL for those using an iDevice typing a sentence with that many directories would not be welcomed. Maybe better to offer a tinyurl like this to your tour. tinyurl.com/tw-tour the shorter and the less you have to switch between keyboard screens the better.
You will find more information about the limitations in the TW Help documentation (F1).

Yes, I used all lowercase letters - the test tour is http://www.brockworksinc.com/_auto/iview3d_reish_insulation.html I use pop-ups for floor plans which I suppose will not work on mobile devices. This particular tour does not need to be mobile, but I definitely have others that need to be. Thank you for your help - I saw another post on the forum from someone with the exact same problem.
