If you are looking for a larger tent in the class you are looking for, I might suggest this one: https://www.amazon.com/gp/product/B00J955FH0/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

It only requires a very minimal amount of work for sealing vents. There are no open vents at all, but two of the windows only zip up on the sides with the top being secured by hook and loops. I used a strip of velcro to replace the hook and loop to get full sealing on the window. Other then that, it was pretty much ready to go. I would also advise getting a shade cloth to drape over the top. The bars on the top of the tent allow it to stand off which provides needed ventilation, plus you can anchor down the shade to provide even better protection from the wind.
