If you look at a similar post on the Desire RM page of this forum, you'll see they maybe changing the theme nights early in 2013 there so one would expect it to change at Pearl too. We are going mid March and the better half is buying stuff for the themes now listed.
Hope the activity staff confirms soon.
Also is anyone interested in the having the Eyes Wide Shut ceremony at Pearl? We went to it a couple of years ago at Desire RM and while one could say it was a little hooky, those that participated sure didn't
I don't think they do it at RM anymore as it was a staple there for too long and participation was low - but Pearl is a different place and a different time.
