There is also Mariner's musuem in Newport News that is just down the street from the LIving Museum.
Nauticus in Norfolk also has a zoo in Norfolk and Botanical Gardens
Va. Beach has the Va. Marine Science Museum
Va Beach also has the beach,
I personally don't go to the beach as I don't get into water that I can't see through.
Yorktown, battlefields, Cornwalis' cave, there is a house that is usually openfor tours, Nelson house, if you look on the left side towards the top, there is still a cannonball stuck in the side of it.
Jamestown there is a somewhat new part that has recreations of the Powhatan Indians longhouses and guides who tell you about how life was back then as well as a fort.
If you want to go north from WIliamsburg, not sure of how long it takes, but not too long is Doswell and there is Paramounts' kings dominion and inside of that is also a water park.
In the summer it is nasty humid hot
As for timeshares there are a few to choose from

owhatan Plantation, Greensprings Plantation sister timeshares. Wyndam Kingsgate, Patriot's place and Governer's green, sister timeshares. Kingscreek plantation, Colonial Crossings is a newer one that is expanding. I actually used to work at Kingsgate and also Kings Creek also expanding and Powhatan Plantation an older timeshare but I know they remodeled the 3 story units a couple years ago and there was a fire and a section had to be rebuilt.
Have a great time!
