The outside bar/club between Harrahs and the Venetian is fun for a change of pace. Bartenders put on a good show. Usually has live entertainment, even in the afternoon. Think its called Club Carnaval or Carnaval Court or some variation of that.
You can spend hours walking through the shopping areas at Caesars and the Venetian and it won't cost you a cent. I know there's a food court at the Venetian that has very reasonable prices for food. But if you really want a great meal and don't mind paying a little more eat at Canaletto in the Venetian.
Stay away from the high end hotels for gambling if you want to find a low stakes table. At night its hard to find even a $3 blackjack table in the name hotels. But there are other places that have that.
