Places to visit in Botswana

Hi,

For the ones living in Botswana, what would you suggest to discover the country?

When you have friends or family visiting you, where do you go with them? What are the must-see places in Botswana, the tourist sites?

How to visit the country in an original way? Any unusual or unknown place to recommend?

What would you suggest for a couple of days of for a week of holidays in Botswana?

Thank you in advance for participating.
