Space Florida was a place visited by the Doctor and Amy Pond. According to the Doctor, the beach had automatic sand which could clean up any rubbish that had been left on it.
After flying the Pandorica into the exploding TARDIS, the Doctor's life rewound to see a younger version of himself and Amy inside the TARDIS, one week ago, during their journey to Space Florida. The present Doctor called out to the past version of Amy, who turned around but did not see him. (DW: The Big Bang)
