Back in my younger days I did this for a timeshare presentation in Vegas and that is exactly how I felt sitting in the open pitch room with the lot of people. At various times throughout the pitch, they'd ask you to raise your hand if you were interested and then they'd whisk you away into a smaller private room to put the screws to you.

I guess you could go, enjoy the festivities, and ignore all the sales pitches. But personally I'd probably feel kinda sad being there, lol, for all the people about to get scammed
