I just got back from my Honeymoon there and stayed in the Aruba Tower and spoke to the Hotel about it. According to them, the Aruba Tower is the last to be refurbished, and its going to be completed in Stages that will be finished by 10/2011
And there was no noise at all ! You dont even know any construction is going on !
We were there a whole week and stayed on the 7th floor (Plaza club ) and it was like a dream !
