Most Inspirational Moment
Day 5 - the stop at Reserva Nacional de los Flamencos then the steady and compelling bus climb to altitude culminating in the magnificent and majestic Miscanto and Minoques volcanoes with their respective lakes. The guide gave us 30 minutes at the Reserva, nowhere near enough. We told him we wanted more and stayed 1 to 1.5 hours which is about right.
The Atacama is much more interesting than you might imagine. Don't think of it a just a desert - it's deservedly a major attraction in Chile with lots of interest and even topped Torres del Paine for me.
Thoughts on Group Leader
A charming man but one who seemed to struggle initially with the size of this group (16) and, in trying to please, was at times indecisive and lacked direction. After several days there were definite rumblings of discontent within the group. He assimilated this and became better so that by the end of the trip he was as he should have been at the beginning. His knowledge of Patagonia was good but less so of the other regions and this is definitely an area which could have been improved. A good solution, which would have enriched the tour, would have been to use a different local guide in the each of the regions leaving the group leader freer to manage, rather than guide, the tour.
Advice for Potential Travellers
I agree with the comments of Peter Rooke, reviewing a different Discover Chile group from mine, on clothing and food. I would, though, advocate lightish walking boots, say three season UK or at least approach shoes. If you choose conventional shoes instead make sure they are stout, as my mother would have said, up to rain, sand, dust and sometimes rocky uneven ground. I found no need of insect repellant at all and nor, so far as I am aware, did any my group. For the colder elements you will need a shell jacket so you can layer up and down underneath with a fleece and maybe a base layer under your shirt. Take gloves and a warm hat. Wind/waterprrof overtrousers are a good addition. You do not need full-on UK winter kit for a February trip; even pre-dawn at altitude it isn't that cold.
Don't be concerned about the amount of trekking; it's high quality but pretty minimal and there isn't a great deal of climbing. If trekking is what you like, this trip will disappoint from that point of view and you would do well to reconsider.
Chile is not a cheap country; think European out of pocket expenses. Budget up to £50 per couple per day and take a bit extra for contingencies. (Hotel del Paine $10 for a bottle of local beer; in the same hotel a fixed price buffet dinner, no other option, at $38pp; Santiago and San pedro pizza for two, one glass of admittedly gorgeous house wine and a Sprite or Cola £40; two airport small vending machine capuccinos £6). Everywhere takes plastic but it's useful to have some dollars cash. As regards pesos I changed $100 at the outset, paid for meals etc with a cash card, and that pocket cash lasted the two of us pretty well the whole trip.
Think carefully about your packing on the internal flights and take whatever you most hold dear into the cabin. If you're travelling as a couple, switch clothing between your two cases. My group did five internal flights on LATAM. The entire group's bags, every checked case, went missing on one flight and three of those bags (mine included) didn't turn up till 24 hours later. On the next flight four of us lost bags again, myself included, for 24 hours.
