SEF urls please help me

[Prince_Oskar]

Hi to all the forum!

I would like some advice from the experts here please.

I am creating my own local travel website which you may check on the domain  www.aegeanvacation.com
username: demo11
pass: demo11

and I am trying to fix properly the urls in order to be SEF.

My main question is:
I have this url http://www.aegeanvacation.com/aegean-islands/lesvos-lesbos/beaches/southern-lesvos-beaches/tarti.html

The url is appearing the path that the user need to arrive and see the beach "Tarti" . Maybe I should make the url shorther and if yes, how you suggest to make it? 
I have some ideas but I dont know what is correct for search engines. for example:
1- www.aegeanvacation.com/tarti-beach
2-aegeanvacation.com/lesvos/tarti-beach
3- aegeanvacation.com/aegean-islands/lesvos/tarti-beach
4- aegeanvacation.com/tarti

I am using K2 and Joomla 2,5 so the main url is being created automatically. If we leave the original url as it is, then maybe I will have problem with dublicate keywords such as "beaches", "lesvos/lesbos", and isnt it too much long url?


Second question for the url of the companies that I include in my portal, now I have for example for the hotels:

http://www.aegeanvacation.com/CHIOS/argentikon-luxury-suites-in-chios.html

Do you suggest any better url please?

Maybe it should be:
1-www.aegeanvacation.com/argentikon-luxury-suites
2-aegeanvacation.com/chios-hotels/argentikon-luxury-suites
Thank you in advance all of you for your answers!

In my opinion, the shorter url you have the better it is recognized by customers and search engines. Answering your first question, i would say that "aegeanvacation.com/tarti" is the best option for promotion. As for the second question, I am not good at inventing new url's, but I repeat: make it shorter and clear.
