The beds at OKW are the hardest beds on earth. They feel like they're made of reinforced concrete. To be honest, they're the reason I'd rather not stay at OKW. Then again, if you're the sort of person who believes a bed should be comparable to the floor in terms of firmness, OKW is the place for you.
The beds at SSR are just fine. They're not remarkable in terms of firmness or softness, just good, middle of the road beds.
