Going to Colonial Williamsburg during a pandemic, in December, while its raining, is not going to be the same experience as you would have during sunnier times. Arriving at the visitor center, there were approximately 4 guests in a facility the size of a shopping mall, with 10 ticket takers waiting patiently in their booths. Colonial Williamsburg itself, a fairly long, but pleasant, walk away from the Visitor Center - had roughly 20 or 30 staff and reenactors spread throughout and was about half or 2/3 closed. Even so, the reenactors outnumbered guests. The ticket prices were reduced to reflect this reality.
We were able to see the Governor's Mansion, Courthouse, Capitol Building, blacksmith, carpenter's yard, a historic house, armory, and several shops selling souvenirs. Be aware, many of the buildings are reconstructions - made in the historic style by carpenters on-site. Staff were universally pleasant despite the circumstances and there were few large groups to be worried about indoors. Some day, I'd like to come back to see the full experience, but it was kind of nice to quietly stroll and have the place nearly to ourselves.
