Update on the Sheraton Hartford at Bradley Airport in Windsor Locks, CT: restaurant and lounge are both re-opened. Lounge is 24x7 by key card if upgraded to lounge floor but is only bottled drinks and minimal pre-packaged snacks. More of just an unstaffed room for bottles of cold water.
Platinum breakfast benefit is coupon for "one entree" at Concorde's Restaurant. They were willing to cover pretty much any single item on the menu with the coupon and, while it doesn't say so on the ticket, coffee was also included. Food decent.
