With all due respect, asking coders to weigh-in on marketing may not be your best move. It may be more productive for you to join some Linked-in software/digital marketing groups, then pose the question there. The simple answers to your questions are: don't just depend on ads, but tightly target the ads you do use; use PR to the extent you make key editors, podcasters, bloggers and twitter personalities aware of your site; make a Facebook fan/site page; open a Twitter acct., follow key people in the travel/hospitality industry, then get them involved... it's a lot of work. The alternative, fund marketing and hire a firm to do it for you.

Yeah but anyone who creates a startup has to take marketing into account.

You could have the best website in the world but without marketing or driving traffic to the site makes it a lame duck.
