It would be a very bitter pill for the Castros to swallow. Then again, if it is their (or their successors') intent to re-establish Havana as a major tourist venue, it could not happen without casino gambling, considering all the competition in the Caribbean.

BTW: Castro re-opened the casinos briefly after a protest by Cuba's hotel and casino workers' union. Even hired Joe Louis as the "official greeter." The Cuban Gov't ran ads in US papers saying that their beef was with our gov't, not the American people. Nobody in the US was convinced.
