I like Trek more than a little, but the price tag is a little steep, and my time is severely limited.
Already I've gone to the top of the (half-scale) Eiffel Tower, seen the beautiful indoor decor of The Bellagio (where much of Ocean's 11 was filmed), The Venetian, and The Paris, and gone to an art show in The Bellagio called "American Modernism," where I got to see some beautiful Georgia O'Keeffe and Max Weber paintings up close. Today I may visit the Art Museum and see some Basquiat, Warhol, et al, visit The New York hotel/casino, maybe visit a Salvador Dali exhibit, and maybe see The Blue Man Group. Tomorrow I'm hoping for the Hoover Dam, and some relaxing times on the lake.
Last night I spent 45 minutes just watching the Bellagio Fountain show, which is really, weirdly, beautiful.
