Since you ask, I shall tell you that, in general, it is a bad idea to visit Cuba while it is ruled by a comunist government
Why ?
Several reasons. Your money helps the dictators to stay in power. Also, your presence there gives the government an appearance of normalcy, legitimate, and approval
About whether will be enough food at the houses, it depends. We are a very resourceful people. And there is a very good organized black market in Cuba to obtain anything
At the present moment, however, I am not sure about the food. According to the information I have the hurricanes have made the usual scarcity much worse, and poor Raulito is striving to deal with the situation ( I don't mean solve it, just keep the power in his hands )
