Harrah's Freeroll?

[DalaiLama]

I got a promotional deal from Harrah's in the mail. They are willing to fly me out, put me up, and let me play in a free roll. It looks to be about a 50K free roll. 1st gets 10K plus a seat at the 2005 wsop, 2nd gets 7500, and so on. My question is, can anyone guesstimate the total number of entrants, or has anyone ever done this before? I'm thinking somewhere around a couple hundred.
