Very much enjoyed the 90 min nature cruise. It was beautiful and a great way to spend an afternoon. The scenery was gorgeous though we didn't see much in the way of wildlife on this trip, but that's okay.
Staff was very friendly and knowledgeable. I enjoyed most of the narration although I will admit I enjoyed the quieter times when there was just nice music playing.
The inside air conditioned lower deck was very nice and comfortable. The upper deck is shaded but you get a nice breeze coming through.
My only complaint about the Desert Belle would be that they overcrowd the upper deck to the point where it's uncomfortable and no leg room. Take out a few rows of seating, it'll be much nicer. I've been on The Dolly cruise and the upper deck is more comfortable with tables and chairs, but no shade.
Oh, passengers please leave screaming children and over developed senses of entitlement at home.
