Malaysia Bound...or Singapore for Indonesian Visa? (From Bali With Love)

I have to go for another visa run in September. I have been to KL twice, but have been considering going to Singapore this time. I favor KL because I have friends there and the process usually takes just one day so I can get back home to my little one, who I can't take with me because, at 4 months, I still need to get her passport. I hear Singapore is great, though I have to stay at least 3 days for the visa process.

So, I want to hear from you! Have you been to KL or Singapore? Can you suggest good hotels, fun sightseeing and shops to visit in either city?

Any suggestions would be appreciated! Thank you! :)
