In reply to Mike-W-99:
The bunkhouse is setup for group bookings- minimum 2 night stay, and minimum charge of £216 per wing, per night.
There is a pod camping place in Morvich (not sure if it really qualifies as cheap, and I've never stayed there) https://strathcroepods.co.uk/
Other options would be Ratagan, the camping and caravan club site or one of the hostels in Kyleakin (25 min drive).
