Ravenscala

From Tardis Wiki, the free Doctor Who reference

Ravenscala was a planet inhabited by giants. The Doctor told Amy that the people are 600 feet tall and you have to talk to them from air balloons. The Ravenscala Tourist Information Center was made from a hat.

The Doctor was attempting to bring Amy and Rory here when they landed in what appeared to be a 1980s hotel. (TV: The God Complex)
