What to do in the off season?

Now that my triathlon season is over, I am now figuring out how I should train. Before, I had to get so many swims, runs, and bike rides in, because of an upcoming race. How weird it is to actually sleep in. It just doesn't seem right not getting up at 4:30 a.m.. Do I scale back on everything? I mean, my next triathlon isn't for 6 months. But will I lose my speed in the meantime? Thought about taking up yoga, because my hamstrings couldn't be any tighter. Well, I think in the end I will continue swimming, until it gets too cold for me to get out of the locker room in my swimsuit, bike once or twice a week, and put in some serious running miles. I'll focus on running races until next April. Actually, there really isn't an off season for any triathlete I know. Who was the person that came up with that idea?!?
