You nailed the basic 'problem-solution' kindergarten exercise, but calling 'price' a problem for travelers is like saying people want food when they're hungry. Give me more depth than obvious statements.

Your 'Market Validation' slide is just Craigslist spam and CouchSurfing usage, not a market. And that 10.6M 'Market Share' on page 5? Is that your actual share or your delusional aspirations? Because if it's real, why are you even here?

A 10% commission? Great, you can count to ten. But projecting $200M in revenue by 2011 for an 'early' startup is either pure fantasy or you've accidentally stumbled upon a time machine you forgot to mention.

A team slide? Apparently, you believe the product will build itself and money will magically appear. For an early-stage company, this is catastrophic. Who exactly am I betting on, your imaginary friends?

Your 'Market Adoption' is a list of events you *plan* to target, not actual wins. And pointing to Craigslist posts as 'market validation' is like calling a pile of dirty laundry 'proof of concept' for a cleaning service. Show me *your* numbers, not other people's problems.

The design is simple enough not to distract me from the lack of substance, though reading everything sideways gave me a crick in the neck. But dropping Lorem Ipsum on your 'Competitive Advantages' is not just bad design, it's professional malpractice.
