Review for Olympic Casino - Eldorado Prostore Review For Olympic Casino - Eldorado Prostore Google User May 20 '18 at 14:20 Top-notch Vegas experience. Staff is beyond helpful. Everything is clean and perfect. I recommend not trying to check in at noon as you will wait very long for a room that is not ready. One Insider trick is to book through American Express fine hotels and resorts which will get you a room upgrade and $80 a day in breakfast credit Plus$100 and Spa credit.
