I think this is a good idea. Start small and measure responses from early adopters. Make light use of software at first. Use existing tools to build a process before attempting to build an application. Start with friends and family and their friends. Define the real problems that people have with current resources. What provides the most value to those who use your approach? I have thought about this concept myself. There are usually very fun and interesting things to do and see in a travel destination that are not necessarily the primary, dry tourist attractions. Travel memories are built around social engagements-talking, sharing, learning, experiencing. I think a solution that emphasizes these things would be beneficial and well received. But again, this will take some effort to sort out. Good luck.
