GreyFal - As you're direct exchanging then you'll have the same privileges as the owner so you need to ask the owner to make your request with Cork Owner Services.
I'm direct exchanging my 2009 Spanish units for NCV. I've told Owner Services in Cork that I'm swapping and that he desires a unit close to tne beach with sea views, either 40, 30 or 10 and high floor.
I called NCV directly having had the owner there to request pretty much the same for us and was told to call again 2 weeks before we arrive. I'm trying to make sure the unit I've rented for my parents is next to ours or at least close by.
