Startup: compilation of tourist routes

User story:

a man came to Rome and wants to walk around Rome. He asks our website to draw up a route for him: start from my hotel, walk for 5 hours, visit the ruins of the ancient Roman period, among them there is necessarily the Colosseum and the most interesting sites of the Renaissance. Somewhere in the middle of the walk - lunch in a meat restaurant.

Implementation:

For the city, places (sites) marked with tags (Christianity, architecture, history, ancient Rome, revival ...) and marks (for each tag) are marked.

With the help of a wizard, the user enters his preferences and a route is drawn up for him.
')
All this based on google maps.

Business model

1. Obvious: advertising hotels, restaurants, tour agencies
2. In fact, a universal engine will be created, you can sell it - the New York or Amsterdam city hall, say

Evidence of possible popularity

1. Large volumes of independent (without groups) tourism
2. Google gradually adds more and more walking routes to its maps (but they are Google hardcoded)

I myself will not write such things on my knee, I will not look for investments, for whom the idea is interesting - take it!
