Well, since no one else is living in BP, and since no one in the family will talk to them, and since Meghan and Harry will be surrounded by Palace security and grey men and staff 24/7, and since they can easily be contained in the State Apartments and have to be checked in and out of the gates any time they want to go somewhere, I say yes, let them stay at BP! Give them three meals a day prepared by the kitchens way down in the basements, Give their luggage a thorough packing and unpacking, and make sure the BP bagpiper plays outside their window every morning at 5:30. Perfect!
