From Rick Kovalcik... 

A number of people have complained about marketing spam from the Park Plaza.  The PP apparently kept the email addresses associated with room confirmations from this last year. I've successfully gotten a couple of people removed from the list. (I've also asked that the PP completely stop doing this, but have had no luck with that so far.)

If you are still getting spam from the Park Plaza, you can either try calling 800-328-6242 to be taken off the email list (reference complaint 200605244193 if necessary) or foward the spam with full headers including addresses to me and I will deal with it.

Sorry for the trouble.  I guess in the future we need to add a "no spam" clause to our hotel contracts.
