The folks who run the big wholesale nursery where we shop in Apopka are either from the Philippines or Indonesia, and are Spanish speakers. Luckily, Jim is fluent in Spanish so it's great to go with him. Although they do all speak some English.
Like any state, there are large ethnic communities in Florida - a huge Cuban community in Miami and a pretty good sized one in Tampa as well. Fun to visit, but I wouldn't want to live there unless I learned Spanish. But if you moved to this area, you wouldn't suffer the snowbird traffic like your son does because you don't commute to work, and you'd certainly choose one of the communities that was not in an ethnic area so I'm sure you'd love it and feel right at home.
