Maybe VW dropping hints about Florida and beaches were to throw people off. I believe she was the master planner also . JMO I have a bad feeling once he doesn’t need her any longer her remains will be found .We all know "all criminals come to Florida".... BUT she had been dropping hints about Florida and beaches... So, I am still convinced she is a master planner, so I think the Florida statements were meant to be a disguise. And trying to "get out of Florida's penisula" would still be difficult, if ever spotted IN Florida.
I think they would have had to drive west and south to eventually try to get to Mexico. I just think that makes the most sense.
