Like others have said, stick with it.
I really can't describe how important it is to not get stressed by the weather. Going to Florida is tempting, but what are you going to do when you get back? Even after getting your PPL, you're still going to be hampered by the weather! So just relax, and take whatever the weather-gods decide to throw at you.
If it's any consolation at all (it won't be, but it'll at least show you that getting the PPL isn't the end of the weather problems), I'm in exactly the same situation, and I've already got a PPL and a little over 200 hours. I'm still trying to get my check-flight done at a new school so I can hire a PA28 for night flying. (Already got the night rating, and experience on type - just need one night flight, and one day flight.) I've booked every Saturday since the clocks changed... and flown once! And I've also only flown my Europa once in the same period. But I just head down to the airfield and hang out with other pilots, or stay at home and study, or do some Christmas shopping instead. No big deal.
