Such a beautiful hotel! The rooms are amazing and huge! Decent views in any direction (even if you're on the back end).
The shops between the Palazzo and here are also very nice to walk through - the gondolas are fun to listen to and watch. I will say that the court yard at the end of the shops is a good representation of the courtyard that is in Venice where Lavena is. Just here they won't charge you to sit and enjoy the music.
If you can stay here it's worth it just to walk into the lobby and walk through the shops, also the Venetian theater is gorgous, if they have a show in there DEFINITELY see a show there!
Enjoy.
