Jeez - they should change the website. It states:
"On Grandeur Of The Seas
The Grand Suite comes with a private balcony (except on Sovereign of the Seas̉), sitting area, bathtub and on Radiance and Voyager-family ships, a minibar and complimentary concierge service. "
Yesterday the RCI agent told us that we would get the concierge service. I just called them again to clarify and they said the same thing you say - no concierge. Disappointing. Oh well - no biggie. Thanks very much for responding!
