Many more rooms on Zebra so, yes, that is what I'd request!

The only downside is you could end up quite a hike from the lobby, but you could also add "close to lobby" as your 2nd request.
The DVC rooms on Giraffe Trail are all "Value" villas so if you have a standard studio booked you don't want to request Giraffe. (sorry for the confusion of DVC vs non-DVC!)
We've stayed in 5004 (1-bedroom), 5006 (studio), 5016 (studio), and 5030 (1-bedroom) - all are Values.
Checking my list, the only DVC "standard view studio" we have stayed in at Jambo was #5406. It was a lobby room (directly at one end of the suspension bridge!) with a nice pool view. Loved the location!
I wish I had more information for you on "standard view studios" and where they're located. I think I need to do more research!
I'm sure someone else who frequents this board can provide more information for us!
