This Saturday is the first day of fall so your family may want to go out to visit a local national park, the local museums or even both. Just flip a coin if you can't decide or look at the skies, if it's rainy then go to a museum or if it's breezy and sunny, then go to a national park. Free admission to both but you'll have to go to their websites to obtain tickets. The Smithsonian Institution is hosting the free museum day while the National Parks Service (NPS) is hosting the its own. If you need an ASL interpreter, you can find their contact information on their websites. Ask the ranger to give you an application to obtain a free "Access" pass.
It's only an hour flight, Cuban visa can be bought during check-in at the airline counter before departure, just don't forget your passport. I exchanged dollars into their convertible (CUC) pesos upon arrival. I stayed at an hostel next to the baseball stadium. I focused on videotaping their culture alone rather than being somewhat biased traveling group with their hectic schedule. One day took a Soviet era Lada taxi to outskirts of Havana to visit a Deaf school. They asked me what we Deaf Americans do with our obsolete TTY as we are using VP nowadays, hopefully some organizations will donate those equipment. I felt like was blasted into the past, surrounded by all those vintage automobiles.
