My hope is that eventually the web, data mining and online applications will make arranging vacations (especially to the beach) trivial. One problem that beach goers must deal with is the balance between how good the location is and how well known. HotMap - a project by Danyel Fisher at Microsoft Research (which I've written about before) - could be used to help with this. By spotting locations that look good (according to Microsoft's imagery) but which haven't been inspected by too many people may turn out to be the secret beaches that we are all searching for.
Perhaps Danyel could create a new version: ColdMap.
