We recently stayed here for two nights as two couples (two rooms).
Firstly- forget about booking an Executive/Club Room. The rooms are almost exactly the same (I upgraded our room while our travelling companions chose not to). The lounge itself is the size of my lounge room and has little if no atmosphere. Average offerings and really not worth the NZD$80pn!
Otherwise, the rooms are clean comfortable and what you would expect from a CP property.
May I compliment the Concierge staff on their enthusiasm, willingness to help and great local knowledge.
P.S. The ALL Blacks stay here and were checking in as we were checking out.
Overall a pleasant stay with a central location.
Sorry, did not eat at Aria the onsite Restaurant, so cannot comment on this.More
