I am currently planning a trip to Asia in April. I have narrowed down my choice to Kuala Lumpur, Malaysia or Phuket, Thailand as I will be able to use airline miles and hotel points for a quick 4 day getaway.

My questions are this: which place has the most to offer?, which has the best sightseeing opportunities?, which is more affordable (food, transport, drinks..etc)? I am a single 30-something male that will be going by himself. I like to have a good time, but hard nights of drinking until 4am probably wont be in the picture.

I like the idea of the Thai beaches for the relaxtion but don't want an over touristy vacation. In Kuala Lumpur, I am able to stay at the Hilton Kuala Lumpur ( any info about this hotel?) which is just a short train ride from the airport to KL Sentral. Are there any good beaches close to Kuala Lumpur good enough for a day trip?

Any info would be greatly appreciated.
