They're supposed to be on the Pembe Savanna. On the Sunset Safari we saw them at a distance beyond fencing. They're named after characters from the old Drew Carey show.
We were in room 5346 last week and the hogs were outside our balcony. Hopefully you can look at the map and sort out where that would be - I can't remember the name of the trail. It was FAAARRRR down the hallway, I can tell you that!
