I also sent an e-mail to the Restort/Marina in May but got NO reply.
But in early June -07 we anchored our yacht on a sandy spot, just 5-6 cables SW of the new marina. By dinghy we sailed up to the marina/resort and asked for details. We were actually looking for a good spot to leave the yacht while travelling back to Norway.
The one in charge were VERY formal and spoke excellent english. We were told that the marina is exclusively for guests only. RICH guests that is! The rooms are 500 -3500 USD pr night. They did not want to provide any prices for the marina itself.
BTW: Have someone gotten more information about the proposed changes in yacht-regulations for The Maldives? The new 21day rule was supposed to be enforced from August 1st.
