I've made the connection many times.
Sometimes the gate is right next to the arrival gate. Sometimes it's way across the airport, meaning a 5-10 min walk.
Usually the WN flight schedules are padded, so you'll normally land a bit early anyway. In most cases boarding is underwayh but not finished. Once they were paging me (duh, didn't they look at their screen and see my connecting flight just landed) as I walked towards the gate, meaning we boarded after the C's with our A-list pases, and sat in separate middle seats.
