What did I enjoy the most in Cuba?
Indeed, Havana is full of beautiful architectures, antique cars and friendliness of people. What did I enjoy the most is connection with local people, non-stop drinking and my first experience of salsa dancing! In Havana, Wi-Fi accesses is so limited, I enjoy morning greeting with my casa owner and also the friendly connection with the people that I met on the street. Second, the price of the water is almost the same as alcoholic drinks. So I drank every single day when I was in Cuba. Last I enjoyed the most is the salsa dancing. It is so dynamic and vibrant. For beginner like me, I may be clumsy dancer. When in Cuba, who cares! Just enjoy the music and dance.
Are there any things that one should avoid doing while there?
There are two different types of currency in Cuba, Cuban peso (CUP) and the convertible peso (CUC). For foreigner, we can only get CUP at the exchange offices. So when you’re buying things, make sure to give back the correct change. For example, If you buy a drink for 4 CUC and you gave the cashier 5 CUC. Then cashier had to give you back 1 CUC not 1CUP.
I use iPhone XS Max to capture all the beautiful scenery.
