Nightly free entertainment. You can take the bus from the strip for 3 dollars each way, its well worth it.
Golden Gate: (downtown) This is the oldest Casino in all of Nevada. Built in 1906, see its transformation from the pictures in the hotel lobby. Get a 99 cent shrimp cocktail while you are there. You need a player’s card to get it but the players card is a good free souvenir that says 1906 club on it.

Treasure Island show is now closed: Nightly Pirate show. Sirens of T.I. is more adult now so consider this rule of thumb:If you take your child to an R movie then its okay to bring them here.

Neon Museum: Its not free but I added to this list because it is very low priced and it is a non profit that provides cheap entertainment.
