We just returned from a 4 night stay at BWI CL. Everything went very well. We had room 4229, which is the first one on the left when you pass the lounge area. It was very quiet. The Boardwalk view was great in the mornings and evenings. We booked a deluxe since a Disney Visa discount made it less expensive than a standard. In the future, I would look for a discount on a standard room because the deluxe was huge for the two of us. Two TVs, two phones, sofa bed (uncomfortable as a sofa and probably not much better as a bed).
When you get off of the elevators, the hallway to the left was blocked off for the remodeling. We were far removed form that area and there was little noise. When outside at a quiet pool, you would occasionally hear some material or debris being moved around. No worse than the landscaping noise you sometimes hear.
The staff was great. Friendly and ready to answer questions. We look forward to a future visit.
