Stateroom 7608 is not one in the new section. They only added about 6 new stateroom on each side of the ship. The Enchantment was had 71 feet added to it. You probably couldn't tell a new stateroom from an original stateroom.
If I remember correctly, the newer rooms stopped at around 7590...just before your room. There were slight differences in the rooms (Others I was traveling with were in the "older" rooms)...We had a shower door rather than a curtain and a newer t.v. Other than that, it wasn't much different.
We cruised on the enchantment last spring break with some friends.....We had a new room and our friend were just down the hall in one of the older rooms. It was a pleasant surprise to have the glass shower door instead of the shower curtain which the friends down the hall had!!! That was the best thing about the new rooms!
