Wind your way through the Grand Canal Shoppes to St. Mark's Square at the Venetian and see the "street performers" and "living statue". Go into the casino's main entrance and take the escalator up one level to get to the Shoppes. Open 10 am to 11 pm (until midnight Friday and Saturday). There is a "Gondolier March" through the Shoppes to St. Mark's Square at 9:30 am and 4 pm.
Enjoy the painted ceilings in the Venetian. The painted ceilings are in three areas; the main casino entrance, the hotel lobby, and the Galleria hall that connects the two. Once you go in the main casino entrance and view that ceiling, the Galleria will be off to your right.
