Your being overly paranoid.
Unless your literally doing walkable distances 5 times a day, I don't think you'll have a problem.
Where I suspect most people have a problem with charging their car is because these days cars are never really 'off', hence trickle chargers have a tendency to pop with unerring regularity. Because the minute you say, insert the key into the slot, theres a drain on the battery and it tries to draw more than the 5amp's that your trickle charger can provide.
Also you don't need to drive around with the electrics off, in order to charge the battery. Your alternator (and indeed almost all alternators) are designed to provide more power than the car requires at any given moment. Ie if i'm driving around and need to turn the lights on, the minute i turn the lights on, the alternator increases it's output in response)
What i'd say to you is...over the xmas period, just leave it..see what happens, worst comes to the worst, then yeah trickle charge it...but take the negative terminal off, which is very easy, just flick the clip and pop it off
You'll have to reset your date and time when you reattach it, but other than that...
But honestly, you don't need to keep it on charge all the time
