motorized watersports are close on good friday, maybe also sat and sun, but that will be decided by the authorities on short notice, sometimes saturday morning.
all amenities offered by your hotel will be available, within the resort you will barely find some effect that it is easter week.
outside the resorts on good friday bars will be closed, but that's only on friday, the rest of the week is party time, our way to celebrate easter week, he he.
some activities like i.e. my sportfishing charter operations from the Marina's docks will run like usual.
happy travel
Mike
