Content type vs Taxonomy for travel site

Hi,

I'm thinking of using Drupal for a new travel journey site. But I am confused as to the best way (usability & SEO) to structure the site. The key purpose of the site is to promote journeys. Secondary is to provide information about cities and places the journey goes through.

I think I want to use taxonomy term "destination" which is for nested terms that are country, city and places (e.g. path = /destination/uk/london/tower-bridge using pattern [term:vocabulary]/[term:parents:join-path]/[term:name])

I want the user to experience the following:
Click on a journey. Read about the journey and see a list of countries, cities and places it passes.
Click on a country. Read about the country and see a list of cities and places it passed. See a list of journeys that pass through the country. Country term has rich text as well as being a category archive/list.
Click on a city. Read about the city, see that it is in country and places within it. See a list of journeys that pass through the city.
Click on a place. Read about the place, see that it is in country and in a city. See a list of journeys that are near the place.

Do I use a content type "journey" and then tag a destination term. The nested path is created country/city/place. But how do I list the other items (node/terms?). It seems I can do this by creating a term reference field to itself.

I found a problem that each time I create a destination term, I then have to go into taxonomy to correctly nest it to it's parent plus regenerate the path pattern. This will be very messy when the site grows.

Or should I have journey as the node and then separate taxonomies for country, city, place. But if I go down this route, how do I automatically generate a nested path /destination///
(/destination/uk/london/tower-bridge)?

Any suggestions welcome?

Thanks

John
