Our teens got the teen bags on both of our last trips (November and March). This was the Portofino. We have received the gifts from the RPH too, although this was some time ago.
I haven't stayed at HRH, but due to the franchised Hard Rock name, I believe that others have reported that the HRH does not participate in the Loews Loves Kids program. So at that hotel, you wouldn't get the kids nor the teen goodie bags. Although, I believe I have read that kids have received blow-up guitars.
Somebody correct me if I am wrong.
