I've been in touch with the calluna which is available from the 5th to the 9th,a bit awkward as we would need to find somewhere to stay on the first night, which wouldn't be ideal for people just coming for the weekend. So can I suggest:
Option A - Flexible
Sat 3rd to Weds 7th - Corrour Lodge. I am checking with the owners on the access and drying points. There is a utility room, which with the addition of a de-humidifier or two might work. There is a wood burner in the living room. £750 total. If the responses aren't positive, can stay in the Calluna 5th to 7th, with people sourcing their own rooms for the first night.
Weds 7th to Sunday 11th - Inchree chalets. These have drying rooms, sleep 6 each and are closer to Glen Coe to mix things up a bit. Crucially, the site has three drying rooms, wifi and can be cancelled up to a week before for full refund. £680 total.
Total cost, £1430, split in an equitable manner of course! £750 non-refundable.
Cost if staying the whole week - £130, £65 non refundable
Cost of both weekends/four nights - £82, £46 non refundable (I've tried to come up with a discount for staying the whole week)
Option B - Non-Flexible
Camisky lodge 3-10 Feb (https://www.cottages-and-castles.co.uk/self-catering/camisky-lodge-1194). Has many open fires, drying room, wifi, right next to the North Face car park. Granted, it is silly and Prince Charles has stayed there. Nonetheless, a good option for sure with easy access and all the amenities we're looking for, but not refundable unless we find someone else to fill it.
Total cost £1891
If staying whole week - £165, non-refundable
If staying both weekends/4 nights - £103, non-refundable
