Review for Plaza Hotel and Casino Review For Plaza Hotel and Casino Google User Mar 20 '17 at 16:39 We stayed at the Union Plaza as part of the " Lovers or Losers" package from Casablanca Express. The hotel has been fully remodeled and the rooms are very nice now. If you want a fun family time, you have Fremont Street Experience right out the front door. The Plaza is Vegas' oldest hotel and is located at 1 Main St. For the price, you get some nice accommodations. View full site to comment or like
