Organise your own trips. I found the ship excursions to be very expensive and could have gone somewhere far better for less. The ship normally docs in port near to the main shopping/tourist areas. Go on, have an adventure.
Plenty of trips to go on but very expensive we did our own thing which is quite easy to d.
Pal up with another couple and negotiate a price with a taxi driver before you start.its easy lots of taxis waiting at the port.ENJOY.
