Note about changing currencies in Cuba (Do Not Take Dollars)

What is the best currency to exchange in Cuba?

In terms of conversion value, the British Pound Sterling and the Euro are the best currencies to bring to Cuba. American travelers (or any tourist carrying US money) should be aware that changing US cash into CUC incurs a 13% fee (including bank fees).Jan 31, 2019.

JG:

The 13% fee is a ROBBERY. How this can happen in Socialist Cuba?

Any comments from recent visitors to Cuba?

I will be visiting my family at year's end.

I may cancel my trip because of the 13% fee. I am a low income retired person.
