The Palazzo is quite easy on the eyes. As the sister property of the Venetian, it shares many of the similar characteristics found at the Venetian. I have been an invited comp guest here and at the Venetian. While both properties are similar, there are some differences:
1) The Palazzo casino is WAYYYY less crowded than its counterpart. It has all the card games and slot machines that you could find anywhere else. Cocktail service is very constant here too, making 2-3 rounds an hour by my blackjack table.
2) I stayed at the Bella Suite over the 2015 Super Bowl weekend. While the suite is a little bigger and newer than the Venetian's luxury suite, I thought the Bella suite wasn't as beautiful as the one at the Venetian. That being said, it's still very very nice.
If you are a fan of the Venetian, but want to experience Las Vegas without the crowds, The Palazzo is definitely a place to check out!
