Is there a more complete service, like a travel agent, to help book an entire trip? e.x. I want to go to a beach in country A, B, or C, on X dates, I prefer Y type of hotel/resort, my budget is $Z, what are my options? So far I've been using a combination of TripAdvisor, Hipmunk, etc, but it's still really painful. I looked into using an old school travel agent, but it seems like they work on commission from the hotel, which doesn't really align incentives. I like Flightfox's model where the fee is simply based on complexity.
