Space Florida
From Tardis Wiki, the free Doctor Who reference
Space Florida was a place somewhere in the universe that the Doctor and Amy Pond visited a week before the events of The Pandorica Opens/The Big Bang. Space Florida had automatic sand which meant it could clean up any rubbish that had been left on it. (DW: The Big Bang)
After flying the Pandorica in to the TARDIS explosion, The Doctor's life rewound to see a younger version of himself and Amy inside the TARDIS during their Journey to Space Florida. The Future Doctor called out to Amy, who turned around only to see nothing. (DW: The Big Bang)
