All the
DVC villas in Jambo (except the club villas) are on the 5th floor.
You could be on Zebra or Kudu trail and overlook Sunset Savanna (Kudu trail) Arusha Savanna (Kudu or Zebra trail) or Uzima Savanna (Zebra trail.) All 3 of the Savannas visible from Jambo have Giraffes on them.
Zebra trail is on the side of the resort where the pool and restaurants are, thus it's a popular choice. Arusha Savanna is the central Savanna and seems to be oft requested.
Your online choices don't really help, IME, as they offer 'higher/lower' floor yet you know you'll be on the 5th floor, so don't waste a choice on that. For a close to the lobby request you may be giving up the best panoramic views of the Savannas which tend to be further down the trails/halls.
For my Dec. 2016, trip I didn't like any of the choices and left the online check in choices blank and got Zebra trail Arusha Savanna near a waterhole - which was quite nice, although I've had that location/view before. I like Uzima view as well, although it is a bit of a hike from the lobby (not as bad as some of the far out Kudu trail villas, IMO.) One of these years I'll get Sunset savanna view on Kudu trail where the small Zebra herd is.
