On Saturday I sent my form and proof of ownership to sbpcl@princesscruises.com and my OBC was posted on Sunday. I am still waiting for the Stock Perks App to validate my ownership. Glad I the princess email still works.
I am currently on Enchanted. In my Balcony room there are 2 American outlets and 2 European ones. Have not had any issues having 2 items plugged in at the same time.
