Since you've brought it up, I've not been to the museum at the Venetian, but I have been to the Sistine Chapel (back in 1974), when I was stationed in Germany and took leave (vacation) to Italy.

The train ride from Munich to Rome was quite an adventure. Rome was unbelievable and as a young (poor) GI, it was all on foot. But, I think that made it even more memorable.

Anyway, I think we can rule out the Venetian at this point. I would.
