At least Obama tried to bring them to them mainland and house them old prisons etc which would've brought the inmates under the jurisdiction of non military courts and thus they would've gotten their day in court, a fair trial not military court bs. Sadly no one wanted to do this, talks of "I'm not going to let terrorists anywhere near my home!" were prevalent and the plan was dead. There is no easy way of choosing Guantanamo Bay given the military industrial complex.
