I think the UI of the Homepage needs to be better designed, I dont like the left hand nav bar and the way you have tried to integrate it with a googleads... I would have seperated them slightly. Otherwise I think the basics are there, for going forward think web 2.0 and user interaction (reviews etc) -thats where the future is I believe. You have a decent amount of back links which is a good start also if you are wanting to look at SEO - although I would considor this area quite competitive now for cruise's.
The blue block of ads on the left seem misaligned with the side menu. You've got some good feeds, though.
