Sledog, I live in FT Myers now, got to see 5 games last year (all losses). It's a good experience depending on your expectations. My suggestion is to see a game or 2 the last 10 days or so of March when you're assured of seeing mostly major leaguers. I live right near the new stadium, it's starting to look really sharp.
Let me know if you have any more questions, happy to help.
