When you check in at the parking booth, they usually signal the concierge desk that you are arriving and someone greets you at your car. They escort you up to the 6th floor, where you check in, no need to wait in the long line at the registration desk. You are shown the Craftsman's lounge, then they escort you to your room to make sure it is suitable.
If it's worth it...that is entirely up to you! I just got a quote for concierge for June $645.00 per night.
To me I love the premium view the best (which you can get without concierge.) I can go without concierge, but not the view!
We were just there in April and did not stay in concierge, but had the great view! We were not treated any different, and enjoyed our stay!
The best thing about concierge is of course the Craftsman's lounge and having access to it! At 9:30PM, they dim the lights, and they have a special patio with piped in music for the fireworks! The best place to watch fireworks is in front of the castle, but if you are sick or tired the craftsman's lounge is the next best thing!
But to be honest, any room at the Grand is great, I mean after all you are staying at the Grand!
