There are SO MANY retirement areas of Florida now.
Being familiar with the Deland, Florida area for almost 50 years, there now are bunches of these 55+ communities. Inland due west of Daytona Beach on via state hwy 17/92 and off of I-10 and west of I-95. Look at where major airports are, airlines flying into the older person's relatives' home cities. Airports there 50 years ago, are basicly GONE today. 2 lane country roads now have 4 lanes of traffic in each direction. And Deland is known for the BIG retirement developments located there now.
50 years ago ... the MCO was McCoy Air Force Base. Now, it is the airport everyone uses going to WDW.
Personally, Orlando is NOT on my 'retire to' locales. Neither is Daytona Beach.
I am still working on the Ft Lauderdale area at this point in time. It is way warmer in the winter than Daytona Beach, on the ocean (unlike Orlando), has lots of cruise ships and still has some OLD timeshares within walking distance to the ocean.
