My wife and I will be spending two days in KL in April coming back home from Mentawai. We were considering staying at the Mandarin Oriental, is that a good choice for a first visit?

We're thinking of going to the Batu Caves and maybe the Central Market on the first day. The second day is pretty open, we're considering a day trip somewhere close like Malacca. We're not really city people so the idea of walking around a big city isn't really appealing to us.
