Just updating this thread. I stayed at the JW Marriott for three days will visiting Medan for wedding. No platinum recognition at check-in, was able to have breakfast at the restaurant in the lobby, it's a decent spread. The elevators are very slow had to wait 4-5 minutes in the lobby trying to get one each night.The rooms were comfortable but the soundproofing is horrible. Called down to the front desk to request ear plugs and the front desk agent stated he had never heard of ear plugs. My wife is a native Indonesian speaker so it was not a lost in translation moment but found the experience odd. Even with its shortcomings it is still probably the best hotel in the city.
