Spent a few day's in and around Changi village last year and whilst the village and creek are as we remember structurally, the village is wall to wall eating houses.
Changi prison has long since gone but the famous POW murals from a hut on base have been well copied and now form part of a small museum of the war time experience of the island. This museum is well worth a look and is very close to the site of the old prison.
The yacht club remains on it's original site and is open to non members and remains a great location to chill and reminisce.
Tried to get onto the base but the SAF security were having none of it - shame
