Question ( I hope I am posting in the right section...new to this). Going on MSC Armonia ( RT/Miami) with an overnight in Cuba in Sept. We booked an excursion for the Walking Historic Havana Tour for the first day ( 5 hours). Any ideas or tips on how to find private tour guides ( that are trustworthy)? Any hints on nightlife ( NOT Tropicana)? Since MSC is providing us with a visa, I assume we get get off/on ship anytime we want. Is Havana safe to walk around at night? Any tips would be appreciated. I can get by in Spanish , but I would not consider myself fluent).
