I was there in April. Saw Shania's show at Caesars and the Faith and Tim show at the Venetian. Liked them both. Also liked the Million Dollar Quartet show at Harrahs.
Went to the pawn stars shop, it is between the strip and downtown, you can take a bus that is close by.
There was a zip line at fremont street, didnt do it but it looked cool.
Ate at the Eiffel Tower, yes it is very expensive, but the food was great the service was great and you get the view of the fountain show across the street. Also ate at Joe's stone crab at the Caesars Mall, it is always awesome there, Joluca who posts here works there, of course you can always visit Joe's in Chicago and South Beach. Also ate at Wolfgang Puck's restaurant at the Venetian Mall. The service was slow but the food was very good.
And I got to see Tommy Gainer at Share night club. That made the trip.
