Space Florida

Space Florida was a place visited by the Doctor and Amy Pond. It 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 during their journey to Space Florida. The future Doctor called out to Amy, who turned around but did not see him. (DW: The Big Bang)
