As much as I love the idea of spontaneity, I still have the habit of drafting up an itinerary each time before I travel, just to make sure I manage my time sufficiently to cover all the places I want to see, activities I want to do, things I want to eat. After all, there are certain places that you might not visit again, ever and it would be a shame to miss out on something just because you ran out of time.
Here you can find the itineraries I have used for my past travels. Feel free to use them as a guide, tweak it to your own preference and ask me questions if you have any 🙂
