3. Hard Rock Hotel & Casino
Overlooking the Gulf of Mexico, the pool at the Hard Rock Hotel & Casino in Biloxi finds itself at #3 on this list. With day passes that range from $20-$25 and a weekly pool party that features live music (one of which is called Tequila Sunday), this is a great place to enjoy a beverage. There’s even a swim-up bar that is fittingly called the “Soundbar.”
