A PP answered your question, but I just wanted to add that the Garden Wing 'access' rooms have access to the 12th Floor/Atrium Club lounge. I've always wanted to stay in one of those access room categories... I've booked them over the years but always end up changing to the tower at some point. Enjoy your stay in your recently renovated 1BR!
I could easily go either way, but I'm a little partial to the Zebra Trail side... mainly because it's a bit closer to the pool (we're usually going to the pool a lot), Victoria Falls lounge, the CL lounge elevators, etc - but it's not like the Kudu Trail is all that far away so I'm splitting hairs a bit. Just makes things a tad easier for trips back to the room if you forget your sunscreen, need to grab something, or whatever. But if the pool or Mara aren't big factors in your trip, my observation is less relevant. I've had good and not so good animal viewing on both sides, so sort of shades of grey there IMO, with some decent variability given luck of timing and proximity to feeding stations.
@focusondisney covered all you need to know... I'll just add we've had bad luck with the "try to head to the 5th floor on our own" method as we have historically had rather bad MagicBand access problems at YC. With maybe a few exceptions, our bands just never work right away... so that means back to the lobby to wait in line (assuming a greeter or ipad manager type isn't around).
It's like an ongoing joke in our family... I always want to try direct to the elevator (despite past problems)... DW says "don't you remember last time..."... we try, fail, back to the lobby, rinse cycle repeat next trip. She's always right.
