We were there on Tuesday evening at it was about half full. Take that with the weather which was very, very windy and cooler that evening by Orlando standards. Also, it was in the middle of the week. Which is when we typically go anyway.
The weekends of course will be more crowded as tourists and locals alike head into Disney Springs for food & drinks. The newness has worn off a bit though I suspect with Spring Break & Summer crowds, the business will pick up as many have not been since it has opened.
We have not seen any waits recently either. Though like I said, it's the semi-down time and Spring Break has not ramped up in the area just yet.
