Whichever one you opt for, you’ll get a hot main meal, and the chance to network with your peers - including senior bods from some of the biggest companies in the UK - before bedding down for the night, before awaking to a cooked breakfast. Ground sheets and survival bags are provided, and if you need a night cap, there’s a cash bar.
Erm, how is that a sleep out? Sounds more like a Jolly. Albeit of a grim nature, with the constant risk of finding yourself downwind of a smoker, or at the mercy of some tw@ with a guitar and about two chords. Best you can hope for is sufficient rain to deter them.
I've done my fair share of sleeping out, including a several-month homeless spell, as well as through choice (when on hols). And early October is not a bad time: well out of peak tourist and midge season, though the lack of daylight is a downer. But there are limits, and I'll take all the commentard downvotes for being a grumpy old git before descending to this.
