Yea. No problem! If all else fails schedule a trip to the North Carolina Aquarium in Manteo to get your saltwater aquarium dosage for your vacation time!
If you decide to take the ferry from Ocracoke back to Hatteras Village one evening I would suggest one of the following places for dinner: in Hatteras Village-Breakwater(AMAZING view at sunset and really nice food, on the higher end side of dining), in Buxton-Rusty's Surf and Turf (A fairly new restaurant that is quite popular, primarily Caribbean style food), and if you go further north to Avon-Ketch 55 (Another restaurant that is fairly popular, primarily known as a seafood grill).
Also, if you have never done this before, I suggest going to the Cape Hatteras Lighthouse at night. It is open to the public and very amazing to see in person. The sky should be clear considering the time of the year, which will make the stargazing phenomenal at the lighthouse site as well. I did this for the first time this year and I have been going to the Outer Banks for years, haha. Here is a picture I took of it.
