3D/4D Ultrasound

Im 32w1d, and was wondering if it was too late to do one of those 3d/4d ultrasounds. I never had one done with my first, 5 years ago..and had every intention of doing one this time around, but somehow time got away from me, and now ive heard that its too late because the baby really does have much room, so its hard to get any clear pictures of her face. This is my husbands first child, and the first grandchild on his side, and I thought it would be neat to have a cd to show his parents when they came in two weeks, but not if its just going to be a waste of money. Opinions? Experiences??
