That's not correct. CL rooms for non-DVC (resort guests) are on 4th floor, in the first pods off the lobby on Kudu and Zebra Trails. Occasionally, a CL resort guest will be in the 2nd pod - usually Kudu Trail, but they try to keep CL guests as close to the lobby (with Arusha Savannah view) as possible.
DVC CL is very limited and that is on floor 6 (where the CL Lounge is located). The 5th floor is DVC (non-CL). I hope this all makes sense!
TreeFalls: Did you link the reservations? That's the easiest way for you to get a room near your parents. Otherwise, your best bet would be to request "near lobby". You might still be on a different floor (2 or 3), but you would be in close proximity, without a long walk down the corridors! Good luck and have a great stay!
