THEME:   none, but four triples & 27 blocks   
GOOD ONES:     Summer, at times   CPA [he adds]   
They don't sound as welcoming as they are   HOSTELS   
Run-off facilitators   STORM DRAINS   
Who's sorry now   RUER [note no question mark (and not Connie Francis' song)]      
BTW:   "…and the ORB below/As hush as death" is not a quote I remember despite having studied 
Hamlet very closely --- perhaps it was "ages and ages hence."      
Literary count, familiarly   DRAC [there was a funny song called something like "Dinner with Drac" by Don Zacherle]         
RATING: 
 
  
  
   Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
