Room 418 must be near some sort of electrical. Moderately loud hum periodically going from quiet to moderate volume. (Not associated with elevator). This was very regular only during hours of darkness. I was diappointed in breakfast options. Apparently complentary coffe only available to Marriot members. I was asked at checkin if I had a number, but wasnt offer option to join or what value of membership was. Might have joined for breakfast options. Instead found starbucks enroute to church for funeral I was attending.
