Day three : entering complete exhaustion but not quite ready to give in...  Using all our magical powers on one more "just the kids" walk around the hotel, breakfast at the "best breakfast in Duluth" - for once Yelp! may have gotten it right. Playing at a super fancy park, searching for kid friendly, historical non-fiction Duluth literature, and settling for a replica of a ship and a mermaid figurine.  Rating 4/5 stars only because we are traveling with 2 train wrecks...
