Alex was really great. He was charming, and knowledgeable, and very thorough. He was responsive (always waiting while we took 2 or 200 more pictures), AND knew when to push us to do one more thing when we thought we had done enough for the day. He really communicates a love of animals, which makes the sightings more fun and interesting. He guarded against anything going wrong and made sure that we had a special experience everyday!
