The pool is shaped like something you'd see in a lava lamp, with two rounded, molten blobs, about 38 metres apart, connected by a narrow "waist" approximately 5 metres wide. Although the ends are not parallel, straight lines, it looks like you could get a pretty decent swim in - as long as there's nobody else in the pool at the time. The hotel describes it as being 50 metres, but to get in a 50 metre length, you'd need to make a 90º turn 100 feet into your lap to reach a third blob that angles off in another direction.
