Still not feeling well, but improving, it looked like my day and tour plans for Kuala Lumpur would also be scratched.
The most I could muster was a shuttle bus ride into the nearby town's mall, where the ship shuttles always drop us. I got off, walked around the mall, had a little bite to eat, and climbed back onto the shuttle for the 30 minute ride back to the ship.
Malaysia is not quite so clean and neat as Singapore. But I suppose it has its charms. Maybe next time it will be a different experience for me.
