Have you traveled with your young children to the Caribbean during the winter (January-ish)? Where did you stay? Did you stay at an all inclusive resort? What was the pricing like? Pros and Cons of where you stayed and would you recommend or return to that resort?
I'm not looking for anything fancy, we don't need children's entertainment, we don't need any of the "extras" that you have to pay for. All we really want is a swim up bar, all inclusive resort, beach access, clean rooms, half decent food, and as much relaxation as we can get with the two boys.
Hola! Yes, I have traveled across Cuba during san francisco bay area hotels the winter with my 7 years son, and it was a very nice experience because of the weather, the beauty of the land itself and the natural kindness san francisco bay area hotels of the cubans. You have to plan carefully your trip but you can choose both, a resort or rent a private apartment or a mix of both, if you stay longer than 1 week. I live in Italy but my 7 years old son lives in Cuba with his mum. If you need some suggestions (to save some money too), I'll be glad to try to help you. Viva Cuba!
