There's not much for kids to do as Cuba is so poor. Beaches are wonderful and a day trip to Veradero is strongly recommended.
If you are in a hotel, make sure it has a pool, and if you are in a Casa, visit the Hotel Nacional's pool.
We went all the way to the huge Parque Lenin on the advice of the guide books - only to find it a deserted wasteland! So beware out-of-date guides.
Our kids loved taking rides in Coco Taxis (little 3-wheel bikes). They also enjoyed the dolphin show, although we probably wouldn't have gone if we'd known the conditions the dolphins are kept in.
Other than that we did the usual tourist things of walking around, markets etc. Not our kids idea of a great time, but we made sure we always did something for them after one of these.
We stayed in the wonderful Sevilla Hotel in Havana and then 2 Casa Particulars (people's houses) in Trinidad and then back in Havana. In retrospect I would probably have finished with the hotel as after 2 weeks in Cuba you really need a bit of luxury! The casas are great however, as you get to stay with a proper Cuban family and they love kids.
Carrie found us all the casas, and she was invaluable. Her site is www.cuba-particular.com and you can contact her at carrie@cuba-particular.com
Cubans love kids! We went everywhere and did everything and heard constant moans from fellow tourists about being hassled and ripped off - we had none of that and can only assume that they left us alone because we had kids in tow. So, they can be an invaluable asset.
