Marina is the new mobile app that allows beach resorts managers to receive online bookings for their beach umbrellas. But not only that! It gives regular customers the chance to earn by sharing their seasonally rented umbrella when they do not use it, and beach-goers the opportunity to spend a day at the beach at a discounted price. For a small affiliate fee, beach resort managers have the opportunity to get extra income on beach umbrellas they have already rented for the whole season, and to attract new customers by offering umbrellas at a discount.
