All my life my mom planned our travels in Excel putting all... where to eat, where to go, prices, everything... Its nice but isnt the same as travel without a plan. Personally i haven't travel without a plan in my life, i wont lie you, but i have saw a lot of Youtube videos of people travelling like that and they always recommend it.. You dont need to worry about time, about place to eat, things that you wont see.. Of course you will not see the same as if you have a plan but you will see the things that you want to see. Example, i travelled to Perú like 4 years ago, and i know the whole Lima, all turistic places and cool stuff (because my mom made the plans), but i didnt went to Machu Picchu, Sacsayhuamán or the Nazca Lines, and i really wanted to see those cool places and more else. So i totally recommend the no-plans travel too, even if i havent do it.
