Good luck. Cuba is not a very business friendly environment. I would suggest that you talk with Sol Melia hotel chain from Spain and see what they say. You will need to partner with the Cuban government so it’s kind of like “You can’t get there from here” type of problem.
Expect A LOT of hassle, upfront costs and delays for the possibility of very limited returns.
I have heard of many cases of foreign entrepreneurs leaving Cuba. That and the fact that Cuba will kick you out after you teach them enough about your business.
