I was on Wonder last July and spent several evenings at the Trellis Bar in CP and wasn't bothered by the big screen at all so even if it presents some noise during the day, I think it is not a problem after dark. I have stayed in CP Balcony cabins on other Oasis ships and have loved it each time, looking out on the park while sitting on the balcony is unique to these ships and to me almost as enjoyable as an oceanview balcony
