Is HF Holidays interesting for solo traveler?

Hi,

I'm interested in walking/hiking in the UK, and have come across HF Holidays. I'm a 32M solo traveler, and I don't know much about this company. I know what you can obviously book single rooms, but I am wondering if I'll just find myself among couples. I'm assuming the demographics skew towards people older than me, especially out of holiday season (September).

I'm thinking of Southern Yorkshire Dales or Shropshire Hills, because Lake District is already unavailable for most of September. I see that there are generally 3 walking options, one of which is always something like 15-20km, so just about what I'm looking for. I'm not looking for a super difficult holiday, just longs walk, and a nice atmosphere.

I've seen some reviews outside of reddit, but I'm wondering if anyone here has any experience with this organizer?

Thanks!
