I don't know that there is an easy way to describe "garden view" rooms in the "garden wing." Not all "garden view" rooms are in the "garden wing" but if we are talking about the garden wing, Garden view "standard" overlooks the lawn, the pool or the bay. (This is not to be confused with the "standard view" room which typically overlooks the parking lot. The Garden view "deluxe" room is a suite - bedroom and sitting area).
Cut and past this into your address line to and look at the lower right corner to see a room number map for the garden wing rooms.

As to quieter rooms, I'm not sure what you mean by that. If you mean the construction noise, there is very little and none at night. I will say that some of the rooms that face the bay (especially the ones that face the canal) might be considered noisy simply because the friendship boats and the ferries travel it and blow their horns before they enter the bay. They don't run too late, however. We were always so tired it never woke or bothered us.
In terms of proximity to the tower, we had the room furthest from it and the longer walk never bothered us. If you want a room closer to the tower, ask for one (on the diagram they are the ones in the lower left corner).
Finally, the best way to get information on the CR is to review the CR thread (cut and past this into your browser:
