I did a two hour tour with my girlfriend. Was kinda bored after 15 minutes. So yeah, there were a bunch of characters interred there, a couple of ok stories, some interesting style and architecture factoids, and a voodoo priest whose vault is as ubiquitous as kilroy. But when Nichols Cage has built a crypt there, that's probably the best indication that a cemetary has jumped the shark. I think it would be easier and quicker to print a list of famous folk there, do a wikipedia search on them, then spend your tourist time doing cooler stuff.
