Dazzling Dorm Heights
Brittany, Cody, Erin, Marcus, and Roger visited their sisters and brothers at the high-rise dormitory on the State University campus. The kids had fun running up and down the stairs and playing in the elevators. The top 9 floors of the dorm are for male students, and floors 2 through 8 are for female students. (The first floor is the lobby and the cafeteria.)
Cody's brother lives on the top floor.
Marcus, Roger, and Cody took the elevator to visit Cody's brother's room. Then they ran down 5 flights of stairs. They realized they'd overshot their destination, so they took an elevator up 1 floor to get to Roger's brother's room.
From Roger's brother's room the three boys went down 6 flights of stairs to visit Marcus's sister. From her room they took the elevator up 4 floors, where they met Brittany and her brother getting on at his floor.
Erin and her sister walked up 2 flights from the lobby to get to Erin's sister's room.
