The walk is because it’s expensive to create & maintain paths, even just some form of gravel rather than paving slabs, I wouldn’t want to go somewhere that was doing an apprentice task level spin on a poor finish lol.
I wonder if it could also be related to getting around planning rules? I'm guessing they probably rely on relaxed rules that allow such temporary & moveable structures in remote places where more robust, fixed buildings would not be allowed due to countryside encroachment. If they were to install smooth, paved paths or drives right up to the accommodation it could possibly put it into a different category where the whole thing would be classed as permanent development requiring full planning permission?
I'm glad to see them being called out and will be interested to see the response from the company, if they respond. If it's true there's no accessibility information for potential bookers who have disabilities then that's poor.
Accessibility is also something that influencers on freebie stays should be covering IMO.
