A PhocusWright study from 2010 found that 40% of (EU) travelers that plan their trip online don't have a destination in mind beforehand. I imagine that this number would be slightly higher for a younger demographic (18-35), which we aim to address initially (thinking 'I don't specifically care where I'm going; I just want to see something new'). The European online hotel & flight sale market itself is valued at roughly $210B. I also expect Wanderlust to be used mainly for shorter city breaks (4-5 day trips) as opposed to actual summer holidays, where most of us tend to have at least some idea of where to go.
I am not sure if the analogy you draw to a local equivalent (and if that fails, surely this would fail) is entirely fair. It's an area I didn't look into specifically.
