Exception like vacations are fine to not run the car. When I was gone for over a month I lifted the car up on jacks so the weight was off the tires. I'd hate to have to buy replacements for my Michelin PS2 before they wear out. I also disconnected the negative battery ground so the battery stays charged. All cars will draw a small amount of current. At 4 weeks my battery will be too low to start and if this happens several times battery life can be significantly shortened.
