Since you are staying at Bally's, which is a Harrah's property. You need to do a few things as a first timer.....You need to go the the TOTAL REWARDS counter....and get palyers card, its free. when playing slots, you insert your card in the machine, or give your card to the dealer at any table game. This tracks you playing and will amass player point, which are redeamable for may things, such as FOOD! lol Their players cards are connected to EVERY Harrah's property in the world. We get offers for freebees all the time. For an example, when I go to CFest in August, I will be staying at three hotels, other than the host hotel, and they are all Harrah's properties/casino's and I will be staying free.....and I have enough points amassed that all my food is free too.
As far as you trip goes and things to do. 3 casinos down from your hotel is the Imperial Palace...its on the same side of the street as well, and they have a huge Automobile Museum there.
if nmothing else....if you go here.....you can see everything going on at any of the Harrah's properties....all the shows, everything.
