We went 2 years ago - we were a family of 4, 2 adults, 1 child and 1 baby and I think we paid around $40? to get in. I remember thinking it was quite a lot for what we saw. We did enjoy the exhibit and my dd enjoyed the ice slides but I think we had seen the entire exhibt in about 45 minutes. We probably spent more time having our free hot chocolate in the Gaylord Palms lobby (which is very nice).
While I thought the sculptures were impressive, I'm not sure it was great value for money. It was also very cold, we needed the coats that where provided and were still quite chilly, gloves would be useful.
