I was ordering my run-in from PA (Amish-build). So first I wanted to go with only run-in. After careful thinking I decided to pay all these extra and add 2 stalls (mostly in case of injury that I have to stall). So now I have run-in + 2 stalls combo. 90% cases I just use the run-in (stalls are locked), but in a bad weather (storm, snow, ice) I'm VERY happy I paid those money and added the stalls. They LOVE them in bad weather - they FLY and jump right in. Because they know they are dry, food and water are always there, and they are big enough so there is lots of space just to lay down and even roll (they do it all the time).
