Do you need a tent that will actually fit 3 adults comfortably?
If so, IMO it is best to bump up to a 4-person.
Now it might seem my recommendation is a bit self-serving because I happen to have a Big Agnes Fly Creek 4 for sale at a very reasonable price, but I think it is solid advice nonetheless. :^)
Different from the CS because it has 1 door, but being a larger tent the door is correspondingly large, and it is somewhat lighter in weight than the CS.
It is a brand new with tags FC UL4 with matching BA footprint, neither of which has ever been removed from original stuff sacks, $300 including shipping CONUS. Bought it for canoe trips and my wife decided she doesn’t want to do canoe trips any more.
PM if interested.
