WL is my favorite resort. If you can, I'd recommend staying at the WL. Your kids will really enjoy it. I've stayed in the Courtyard view rooms, once because I booked it that way and the other time because we were upgraded from standard view.
As far as bad views at WL, they do have some standard rooms that look off onto the parking lot and might have some standard rooms where you can hear the noise from the trucks bringing supplies and picking up trash, but you probably have that all resorts.
I've nevered stayed at POR so I can't comment on that resort.
I'm sure more folks will chime in and let you know their experiences, though.
Good luck and have a great trip.
