Would i be worrying unnecessarily if concerned about leaving my RRS at the airport for 2 weeks while i sod off to sunnier climes next month?

Can i expect the battery to still have enough charge to start when I return at some ungodly hour in the morning after a 13 hour flight?

It's a good 100+ miles to the airport so it should be fully charged when I drop it off and i'll make sure it's in access height to reduce power use (what do people do if using valet parking? Presumably the valet wouldn't know/think to lower it when parked)?

And would single locking it rather than double locking have any effect on power drain from the alarm system? Presuming the official car parks are reasonably secure for either.

I haven't had any battery issues yet but I am surprised sometimes at how quickly the radio/tv switches itself off when watching/listening with the engine off. Merc C220 estate Sport AMG

I'd say it would be fine after a 100 mile drive. I've left mine longer in similar circumstances. I believe it uses less electricity when double-locked, but I may be wrong on that. However, I always leave mine double-locked for security. I don't leave it in access height either, as I have that disabled on the dealer's recommendation having deployable side steps, and it's still been OK. (I know I could enable it, but it never strikes me).

Park up, double lock and enjoy your holiday
The AA or LR Assist will help if you need to on return
Only use an airport approved car park though...worth the cost for piece of mind. Business parking at T5 in Heathrow is superb and has pods to transit direct into terminal Visitor from fullfatrr.com

I had this problem before and after waiting for 3 hours for AA to turn up (no LR Assist in this part of the world), decided I would do something more positive about it. So I purchased a NOCO Genius Boost HD GB70 2000 Amp 12V UltraSafe Lithium Jump Starter, from Amazon. Small piece of kit, RETAINS a charge (for months and months) and has enough power for 40 starts, or so they claim. Have used it twice, once again at the airport and recently when my neighbours Mitsubishi Pajero had a flat battery. You can also use it to boost boats or other battery started equipment. It is REALLY powerful for its size, and despite being a bit pricey, worth it for the peace of mind.

Hope this helps,

When my dad had this car it would sit for 6 weeks at a time without being started, then 1st turn of the key it would start. Short trip to the hospital (5 miles each way) and it would sit for another 3 to 4 weeks. I would have it for a couple of weeks then to run round, never had a battery problem.
I will be leaving it at the Airport early next year for a fortnight, not got any worries about it. Enjoy your holiday

Got back to Gatwick yesterday morning to find the car waiting for me in the valet parking area, all ready to go.

Valet parking is actually cheaper than on-site long term at the moment and car was well driven and looked after, as recorded by dash cam. Merc C220 estate Sport AMG

I have recently found out how to connect up My Maplin solar trickle charger to my L494 after 6 years of not being able to trickle charge batteries on my FFRR, 2 Evoques and my current RRS. I put a post in the L494 section with photos showing how to get around the dead sockets when the power is off. This is the panel I use, it is more than enough to trickle charge the battery if the car is not under cover - it needs very little daylight too.
