If its getting used on the weekends then that's fine, also 2 weeks is not too long. Don't start it and just let it idle, this is much worse than it sitting for a few weeks. We have a car at our holiday place, have owned it since 2000. It sits the whole year and gets used in Dec, sometimes its 2 years, we just service it every year or 2 and keep the battery charged. It starts first time every time.
Also the jeep up here in jhb, my dad uses it every now and then, usually once a month. Just keeps it connected to a trickle intelligent charger when not in use.
I would say if its going to sit for 3 to 6 months at a time, I would get it on some jack stands to keep the tires from flat spotting
