The itinerary was packed and plentiful, but the places I wanted to visit were excellent, the fireworks boat had a comfortable viewing spot, and the view was breathtaking. The only downside was that the weather wasn't as I expected; it rained all day.
The ranch is a bit small, but the bears are funny and intelligent. There's a cable car nearby that you can take to the top for a view.
