This is my recent quote provided by a wedding planner for Maramao Beach Club:
Add $400 USD to book the location
$44 USD per person for National Open Bar for 2 1/2 hours + 10% Taxes + 15% Services
$66 USD per person for International Open Bar for 2 1/2 hours + 10% Taxes + 15% Services
This seems like a big jump from Dijawana's experience.
