Planning a trip takes time and effort. Web app Plnnr can help you with that task by automatically suggesting a trip itinerary with things to do, places to eat, and where to stay based on your likings.
To get started, select where you're going, for how long, and choose a theme like kid-friendly, outdoors, culture or "best of". You can also then select how intense a plan you want — ranging from a light restful trip to one where you wake up early and see the whole town. Finally, you choose your hotel luxury level and the tentative itinerary is generated for you, all centered around your hotel location and interests.
The sample itinerary I created for Paris included the obligatory Eiffel Tower and Arc de Triomphe visit, a walk to several nearby museums, and visiting famous shops on the first day. It felt like a complete plan (though I didn't see restaurant suggestions), and only took a few minutes.
For your next trip (or just to fulfil some wanderlust virtually), Plnnr looks like a very helpful tool to get you started.
