I took my teenage kids to Vegas last summer and we ended up staying at the Palazzo. It is a sister hotel of the Venetian (located side by side) and in my opinion, better. Rooms all have sunken living room with plenty of space, and the 2 hotels share the same swimming pool complex.
We got our hotel at a very good rate using Hotwire. When you book on Hotwire, you actually don't know the name of the hotel until after you book. However, you can identify your hotel by comparing the info on Hotwire to data on this
Hotwire hotel list for Vegas. Both the Venetian and Palazzo show up in Strip North zone. Look for an "all suite" hotel with a casino, and you're almost guaranteed to get the Venetian or Palazzo. Please make sure it has a casino or you could end up getting the Trump hotel which is off the Strip and not what you want. Good luck!
We're planning to go back this summer and I'm already eyeing the Palazzo/Venetian.
