The number of trip planning sites have increased drastically and almost all follow the same approach:
1) Give a you list of predefined activities for x location spread over n days - almost everyone building their own wikitravel
2) Get suggestions based on your social feed
I find this extremely boring and generalist as these sites churn out similar touristy itineraries for everyone.
So having set the context, would love to know what sites the community uses to plan their holiday travel. I am looking for destination planning and not hotel/flight booking sites.
