I've been to many of the exxxotica expos in NJ - in fact this is the first one I'm going to miss.  I can tell you that there are LOTS of fun porn stars who are going to be there.

My best suggestion: go to TheLuxuryCompanion.com and compare Adonia's list of stars with the list of ladies who are going to be at Exxxotica (listed on their website) and find one you like.  Then give Adonia a call and I'm sure she'll be able to set something up.  

Some of my personal favorites who will be there:
Amy Brooke
Christy Stevens
Sunny Lane
Sarah Vandella
Aleksa Nicole

There are also a few UTRs attending but, obviously, I can't mention them here.

Disclaimer: I do not work for Adonia/TheLuzuryCompanion - I'm just a very satisfied customer
