Frequency of Trop (AC) spreading $10-20 ?

[smb394]

Well, I guess the title of the thread says most of it. I'm heading down to AC this weekend, and my friends (non-poker playing) want to head to the Trop (I say Borgata, but anyway...).

I've seen from searching through this forum that $10-20 is spread only sometimes at the Trop. Does anyone have any idea what the chances are of this happening on a summer Friday night, or is this just completely dependent upon demand of people showing up? Thank for any help.
