I believe that the kind of trip you will have will largely be determined by how much you spend on each item in [Travel Expenses].
Originally, it would be expected that you would list out the things you want to do and the policies you want to accomplish, and then accumulate expenses. If I had this budget, I would have been able to create a pretty ideal plan.
Honestly, I would like to spend a lot of money on everything. However, in most cases there is not enough leeway. On the other hand, if you save too much on a short itinerary, you are likely to end up not being able to do the things you want to do.
Therefore, we will start to include points for compromise and cost reductions.
For instance,
Visit all World Heritage Sites (1154 items)
→ Exclude places that cannot be accessed or are difficult to access (900 items)
→ Select the place you want to see (30 items)
