Place looks great. Wish I lived closer ;)
While there are a number of tactics that could get you more people coming to your website, my concern is that those who do visit are unlikely to complete a booking given the number of steps in your registration process.
I think there are a number of "quick wins" (things that you could do to increase sales that don't require too many changes to your existing website) that are possible by making the existing website more efficient.
I'm not a travel expert but I am experienced in online marketing and conversion optimization. Happy to talk to you in a call if you're interested in understanding these quick wins.
