I'm at a convention right now that's taking place at Bally's/Paris. Bally's has a room that's probably between similar size and 50% larger than the one at the Trop. In the convention center part, which is actually right on the Paris side of the walkway between the two hotels, are a room probably about the same size, and another into which you could probably drop no less than 10 of the Trop convention room.

Of course, good luck getting room rates.
