Hi there,
I would suggest splitting the holiday in two. If you are arriving in
Havana, I would assume you already have booked
accommodation so, you could stay the first week in the capital.
Havana is a fantastic
lively place and you will definitely enjoy a ride in the 50's classic American cars. Then, you could head to
Varadero beach, which is one the best beach spots in
Cuba with its white sandy beaches.
Hope this helps
