I not offense because for a tourist or people who live outside Cuba is easy to get confuse by government propagand.
For your info I live in Cuba and almost all hotels belongs to Cuban Army Forces so that workers if say anything else don't be blame the embargo have the high risk of being fired and even get a judicial sanction.
1000 people is in jail for pacific protest against communism and government. The legal process was shitty: fake evidence, fake witnesses and exagerate sentence based on the retaliation desire of give an example for the rest of us. This not prevent the disguss and other protest (small ones due instant repression and internet shutdown).
Yes Cuba is beautifull country, yes embargo exist but is not the main problem. Was the Communist government to prohibite cuban people go to hotels for decades (right now make an economic apartheid charging hotels in USD only knowing the people is unable to have that currency), is the Communist that don't allow freedom of speach, that make illegal move food (even small amounts) from a city to other, that make illegal the workers right to go on strike, that deny enter or out the country to cuban citizens just because they ideology, and a long etc.
If you are unable to see that the Cuban government and communism is just a totalitarian system, if you are not capable to criticize in Cuba all things you criticize in capitalism or you never allow happend in your country, sorry for this but that maked you an hypocrite. None people who defend working class, if they have truly commitment with the workers, should defend Cuban system and government.
CUBAN MINIMUN PENSION: 6 dollars per month
1 pound of rice: 0.8 usd
1 pound of pork meat: 1.6 usd
1 egg: 0.25 USD
That is not fault of embargo. Luxury hotels that remain emptys are build here with 100% cuban state capital, luxury cars are buyed in USA for political use, but for food and medicines are not money. What a curious thing eh?
If your sister or you come to Cuba again, go outside the touristic or hotels zones, maybe you see the real Cuba and not the magazine one.
