How much cash should I take to Cuba for a long weekend?

American here, can’t use cards in Cuba. Surprising my wife with a weekend in Cuba for her birthday. We’ll be in Havana from Friday morning until Saturday morning when we head to Viñales for the day, then back to Havana Saturday night until late Sunday afternoon.

Not looking to spend a ton of money while we’re there but not on a tight budget either. Don’t want to make ourselves targets for robbery with lots of cash on us.

Anyone have experience with this?

Also, feel free to hit me with some recommendations for things to do while we’re there!
