Unless you have room to use a template guide do not use a rotocutter.. they are near impossible to guide by hand without an edge to work against, and they are so torquey(?) that they can take off on you and leave a mess behind.
A large holesaw as suggested above will work better. Also the fittings pointed out by Thumbs should look alright, probably better than trying to hide a cutout any other way, and it's reusable at a later date.
What's on the other side of the bulkhead? Can you cut out there in a less noticeable area (such as a settee top or inside a cabinet)?
