This is our favorite NC destination and now an annual must-do. We've been to the twilight tour and the morning (but still very hot) tour. Of the two, I strongly recommend the twilight tour. The animals seemed more relaxed and available, and in the morning, they are easily distracted by the food truck. But, both times, we've seen most of the animals (the ones on the tour, anyway - some are tour-shy). We're partial to the tigers, but they have lions, ocelots, cougars, bobcats, servals, etc. Most of them do have sad histories, but they are now in a good place and are well cared for.
