We have stayed at SSr, SSr Treehouses, OKW, AKV, BLT, GFV.
We have never really had an issues with room cleanliness. The only thing I didn't really like was OKW grout between the bathrooms tiles was badly mouldy.
We did however find this past trip cutbacks were an issue. Not with cleanliness but with supply. On trash and towel nothing was replenished, no soap, no shampoo, I even had to call for toilet roll. Not at 1 resort but 3. SSR, AKV and GVF so it must be a management directive. We have never not had spare toilet roll left before but this time 3 checkins and 3 trash and towel and never a sore toilet roll left in the room only what was already started on the holder.
