I have lived in the Orlando area (actually NW of Orlando in Apopka) and now live in the Tampa Bay area (GO BUCS!).
I used to say I liked the Orlando area better than Tampa Bay, but the longer I live in Tampa Bay, the more I like it. The only thing I don't like is that is a BIG area for the snowbirds. From about November through March, we have LOTS of elderly people, out-of-state cars, which means SLOW and erratic drivers!!!
Orlando is a little more touristy, what with all the theme parks, etc. You'd be closer to your mother (Winter Haven) if you lived in Orlando, though.
Best of luck! Florida is WONDERFUL! We've been here 13 years and LOVE IT!
