With a Grand Suite you get concierge service and free drinks in the concierge lounge from 5pm to 8:30pm on ship the offer it. However, Rhapsody is an older "Vision" class ship and doesn't offer what I just mentioned. You'll love a Grand Suite, but in my opinion it's not worth the extra dollar spent…I would probably go for a Junior Suite; it has a tub and the room is half again the size of a regular balcony cabin. I was in a Grand Suite on a 14 night cruise last month and we loved it. However, we would be just as happy in a Junior Suite, especially on a 7 night cruise. Too bad your cruise isn't on a "Radiance" class ship. HERE
