The ballpark sits within walking distance of the main Biloxi casino frontage, which is the single most useful thing about its location. If you are staying at one of the beach-road resorts you can walk over, which takes the parking question away entirely on a busy night.
Tickets are cheap by the standards of any professional sport. Most seats have sat in the low double digits, with premium and group areas above that, and children's and military rates have been offered. We do not print a number because the club revises them, but the practical point holds: a family of four gets an evening out here for less than a single dinner on the beach road.
Food inside is ballpark food with local variations. Do not expect the seafood the city is named for at a serious standard; the good shrimp and oysters are at the restaurants on Point Cadet and along the Back Bay, and that is a separate evening.
Parking is available around the ground and in nearby downtown lots. On a Saturday with a concert at one of the casinos it fills, which is another argument for walking.
