I held off completing this as I wanted to be fair to both hotels and compare like for like, which necessitated another visit to the Le Meridien with an executive room booking. Having now done that I have a few thoughts:
1. Rooms are small in either hotel by local standards, with artificially high ceilings boosting the sqm count by a bit without being useable unless your high tower.
2. Executive lounge, Hilton wins on style while Le Meridien wins on food choices in the evening, although its fair to say fried macaroni was not my first choice after a long J flight.
3. It gets a tad bit annoying that the lobby is not on the same level as Sentral, while I am sure most may arrive by taxi, using the LRT or KLIA express means sharing one of two small lifts up to the lobby level for either hotel often with stops on each floor of the car parks, not much they can do to fix that now but it's still a small gripe.
If I was to pick a winner I would take the Le Meridien for its breakfast and better rates, I thought MYR$349 was good value as a star pick for my stay despite being only SPG Gold, if I was top level in both the suite options might change my mind. Would either hotel be my first choice in KL for that chain, I would honestly have to say no, the Double Tree offers better value for Hilton Diamonds especially during the week with its hawker food court offering cheap eats, while the Sheraton rooms have the older style charm but with far more usable sqm of room, with both being closer to KLCC should shopping be on your mind.
As it stands, any of the four hotels make for a great choice given the room rates in KL so my preferences are based on small differences, and they all make you feel welcome. With Aloft opening Friday, SPG matteress runs will be very easy and cheap given you get credit for up to three rooms per night, which could be another deciding factor for some.
