I think there is, if by "Jefrries tubes" you mean this:
There's room for a WHOLE DECK between those windows. Going by the xbox/ps3 game, though, I think that the deck structure of this Enterprise doesn't have the 3 meter layer cake concept we're used to; I actually think each "deck" is a habitable space about 6 or 7 meters high, containing corridors and rooms, air ducts and cable trunking in the floors and ceilings, high bays and low bays for some labs and machine spaces, water pumps, heating and cooling equipment, etc. IOW the main reason for the deck structure is probably the fact that THIS Enterprise does not have paper-thin floors and ceilings and that the space between one deck and the next is packed with equipment.
