I have not seen Jubliee, but did see the Tropicana show the year before it closed. [really the "nudity" is quite tame for what you see on TV/movies these days] You have already bought your ticket, so I would just enjoy the show and know that you are probably seeing the last "Vegas Style" show left. Who knows how long it will last.
I really do enjoy getting a glimpse now and then at the "old" Vegas. We go to LV every year and it seems things are continually changing and not always for the best!!
It took years for us to go off-strip to visit the Liberace museum ... I think it went out of business within the next year or two after seeing it.
So, you may be glad that you took the opportunity to see this style of show that used to be the staple in LV, before it disappears completely!!!
Enjoy.
