I don't want to track external links. I just want to know where they go when they leave. Is that possible? Can I do this with a cookie?

I work for a travel site and we have pages for properties in destinations and am trying to decide how best to organize the URLs basically we have our main domain, resort pages and we'll also have articles about each resort so the URL structure will actually get longer:
A. domain.com/main-keyword/state/city-region/resort-name
_    domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village_ _   domain.com/main-keyword-in-state-city/resort-name-feature    _
_   domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village/kid-friend-pool_ B. Another way to structure would be to remove the location and keyword folders and combine. Note that some of the resort names are long and spaces are being replaced dynamically with dashes. 
ex. domain.com/main-keyword-in-state-city/resort-name
_      domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village_ _      domain.com/main-keyword-in-state-city/resort-name-feature_
_      domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village-kid-friend-pool_ Question: is that too many folders or should i combine or break up? What would you do with this? Trying to avoid too many dashes.
