Hey I wanted to shout out a huge thanks for letting me know about this. I happened to be in Rio from the 8th to 15th, so was able to take advantage of the party 3 of the 4 nights. They had around 500 guests on Thursday, Friday, and Sunday, and about 700 for Saturday (featuring Nadia Comaneci). Catering was good, drinks were great (and unlimited), staff was excellent. It was a great venue (amazingly at one of the nicest, if not THE nicest, hotels in Rio, the Copacabana Palace).
A little anecdote: At the mens Synchronized Diving event on Wednesday the 10th, a woman asked me about the events I'd be going to, and I mentioned the Chase United party, asking her if she had this card, because it sounded like a nice party.
The woman she was with, previously silent, leaned over and rolled her eyes at me: "YOU aren't getting into THAT party. My husband put up the TVs for those events, and believe me, they don't just let
ANYONE into that party."
I challenged her that I'd read the Chase Visa promo online and it sure looked like I was going to be able
to attend. She laughed and said, "Haha, let me know how that goes."
So just to let her know, it was fantastic.

And as Edina Monsoon said in one of my favorite AbFab scenes, "You work in a shop, you know. You can drop the attitude." Just switch to: "Your husband puts up TVs, you know. You can drop the attitude."
