I wrap them all here, carefully sort them into separate bags for each child with their name on, then dh packs them into the boot, rearranging them as he sees fit, muttering about how much money we've spent, and that they have far too much c**@ already. We then pack everything else around their feet and hope that they don't wonder why the boot is full.
At the other end we get everything out under cover of darkness, I have tizzy fit when realise 6yr old has rubber duck in stocking and 2yr old has enough hama beads to constitue a full meal. The children then dispense of all the packaging, we leave a few, gain a few, pack up again, move to next location, unpack the boot to find the 'favourite' toy which is inevitably a 20p stocking filler which has fallen to bottom of boot. Leave a few, gain a few, drive home and unload back into house they first started in.
Don't know how will fit dd1 scooter in, takes up half our bedroom as it is, probably 90 percent packaging though. Hope that has filled you with joy and excitement about being away from home for Christmas!
