I didn't include BC or YC or POR in my list because the rooms do not all have a day bed or murphy bed and priority for those rooms is given to families of 5. It's taking a big chance requesting it. I won't book a room unless I can pay for exactly what I need. If I'm dependent upon a request for a NEED (not just a want) then it's too much of a risk for me. I wasn't aware that all BWI rooms have day beds. I thought it was like BC/YC in that only some have them. Good to know I can consider that as an option.
