Cuba Travel Tips?

I am headed to Cuba for 2 weeks in Dec. with wife and 14 yo daughter. Joining other family there. Havana for a week and have a week which is still unscheduled.

There is a music festival the week we are in Havana.

What other part of island is best, most interesting must see etc. ?

Great eats?

Best Rum and cigars to bring back?

I am getting a new Camera for the trip that I am really excited about: Fuji X-T2. So, looking for great scenery is definitely on our minds.

TIA for any input!
