If it were just you your best bet would be a wedge. Its got more then enough room for 1 person. There are some big wedges but are less then practical for I person to set up. Even a small wall tent can be a pain to set up by yourself. People will help you but I try not to count on it.
A 12 foot tipi will sleep three ok, warm in the winter and can be set up by one person with out trouble. It is a pain to transport. A 12 foot pyramid is easy to transport, easy to set up, roomy and can be fit for a stove.
Wedges are most hc, we know they went to rendezvous. Tipis were at voo, but were used by Indians. We cant prove wall and pyramids were invented yet.
Many eastern events wont let you have a tipi, and some western events frown on pyramids,and bakers, that also cant get in to some eastern events.
Panther primitives and tent smith offers a lot of info PP makes tents from Roman and Viking times to the second world war.
I don't know how old your son is but for the price of a wall tent get 2 wedges, if you and your son or you and your wife you could camp in one wedge, if all three of you your son could have his own room, with a common space between the two tents. And wedges are hc for the whole of European American history.
