The Venetian is a nice hotel, albeit an older version of the Palazzo. The rooms are large and have nice furnishings, but we couldn't help comparing them to the rooms at its sister hotel, the Palazzo (which has newer and more modern carpeting, bedding and other amenities.) If you have a choice between the two hotels for the same price, I suggest that you choose Palazzo.
One major negative about the Venetian--VALET PARKING. They took over an hour to retrieve our car. It was Sunday night and they only had three people working to retrieve cars. People at the valet desk were screaming and yelling and I heard one gentleman threaten to call the police when they would not let him retrieve his own car. Another man missed his flight due to the delay. I have never had any problem with valet parking at Palazzo, but for some reason the Venetian valet was seriously understaffed when we were there.
We ate dinner at Morel's in the Palazzo, which was delicious but expensive. The service was excellent and everyone enjoyed their entrees. The cheese plate appetizer was fantastic, too!
Overally, we enjoyed our stay at the Venetian but we would avoid the valet parking at all costs.
