I ended up spending three weeks anchored off Georgetown. I needed the break after that Darwin Singapore non stop madness. I got really lucky with the winds after hearing a few other cruiser's accounts of how flat the conditions were around the Java Sea.
I visited two anchorages in Langkawi. Kuah and the back side of Pantai Cenang. Loads of other cruisers spread around the island. At least three marinas. Langkawi felt like a "nice" place to cruise - many beautiful anchorages, decent amount of facilities, duty free alcohol. So nice it felt a little bland to me so I left.
