Hi there, while there are many places on the beach in Manuel Antonio, many are quite expensive. Flexibility... not sure what you mean by that. Full board, half board, early/late check in/out??? I do know Jaco is closer to the airport, less expensive, and there are many secluded spots for a beach ceremony in the town just south of there, Hermosa. They also enjoy a much more active nightlife. Hotel Docelunas has done numerous weddings, both on their spectacular grounds, and on nearby beaches. They also can be flexible as to meal plans, etc. Good luck....
