Your room will be nice and don't worry about construction. We never heard anything as we were gone most of the day. The only time I heard anything was when I was at the pool and it was a light banging off in the distance (ten floors up to be exact) as the workers installed the new railings on the 10th floor balconies.
Really, there was no noise, no dust, nothing.
You'll love the CR. I know my family did. Talk about being close to ALL the action!
