My wife and I toured with Lana, "La Cubana," this afternoon and enjoyed it very much, There were 13 people on the tour in total and it worked out well with the food, drink, and desert tastings. Lana has a great personality and background and it was a lot of fun hearing her stories and learning a little about the Cuban culture and the origins of Little Havana.
The weather was already a bit humid and very warm in the sun at the end of March. You'll be outside walking for the majority of the time, so prepare accordingly.
