I like the idea, but going to your site I can't see your value proposition.

Your key differentiator is that you combine hotel+flight prices and you should make that more clear. Also it's not clear if your hotel prices are per person (with the assumption that there's two of you sharing) or per room.

I also agree with several of the other comments that you need to focus on your target audience much more. I'd recommend targeting 20-30 year olds without kids with disposal income who are looking for somewhere to go for the weekend.
