Your site looks all right but you have to do more work to it...Try looking at the competitors sites to see what they are doing. Good Luck!
Your site too heavy! I think that, now there are many wordpress themes to design aout travel website, so Seo better, site loads faster!
I think you can add Facebook fan page, Twitter ,Pinterest and other bookmarks on your website to make interact with your potentical customers. I agree with Sacredhoops point that your website seems dark. You can make it better.
Hey Bro, It's a good looking site. Maybe you need make your site more lively and fun because it's a travellers site. Add more colors on it and please minimize dark colors.
You need to add a blog this way you will able to generate content thus improve your site ranking and more so increase your visitor retention.
That purple is a little distracting but overall, looks like a well put together site. I would test different colors for the top though
I think the color combination could be better. The other things are good except it need to have more content.
I do like the layout. I would copy the other travel sites with easy navigation for all inclusive packages, last minute deals, etc...
