...I'll add my 2c too. Size matters. For one person get a 2 or 3 person tent, for 2 persons get a 4 person tent...etc. It's nice to have a little room for your clothing and other gear on bad weather days, and in my opinion a fly and vestibule are important. Prepare to spend some coin on a decent tent that is light, strong and material that resists mold and mildew.
I like the circus tent suggestion except that you might have trouble shifting with clown shoes, the B's horn is louder that a red bulbous nose, but worst of all you'll seem attractive to bearded ladies....on the flip side you can hydrate on the fly from your water squirting lapel flower and you won't need to worry about sunscreen.
