Darin was an excellent, fun guide. He handled out large group well, making himself audible to all. MOM boat ride was the perfect start, followed by Cave of the Winds, which is absolutely thrilling. Access to free shuttle for the rest of the day is included, so I recommend getting on the first tour of the day at 9 if you want to take advantage. We did, later shuttling to the Whirlpool Trailhead and walked the Gorge Rim Trail, heading down the stairs to lounge on beautiful flat bedrock right next to dramatically rushing water two miles below the falls. Moderate hike with about 350 steps down and then back up. Great day for the three of us! Mom, with two active teens.
