Ok, so Akl is our favorite resort. So much so, that we are now
Dvc members here. You didn't mention your budget in your post, so I will break it down for you like this.... Although I may confuse you even more, lol....
Savannah view - totally amazing to relax watching animals from your balcony. It's great to drink coffee in the morning, or wine in the evening... BUT, if you are the type to run around all day at the parks, you may not spend a lot of time out there. There are many, many viewing areas all over the resort to check out the animals. Don't think your balcony is the only spot. Also, the resort is very large, and a Savannah View may be a long walk from the lobby, pool, food, and bus stop.
Pool view - Much less expensive than Savannah.... You are guaranteed a great location in the lodge... Close to the bus, lobby, laundry, gym, food, and of course, the pool. During the afternoon they have activities by the pool, which may be loud, in case you have small children who need to nap. There are also animal viewing areas near the pool, so you won't need to go far.
IMHO, if you can afford it, and you think you are only staying at the Lodge this one time, I'd probably choose Savannah View, for the experience. I would request a room close to the lobby though. But, you certainly can't go wrong with a pool view... We request it often! Sorry if I made your decision harder, lol. Good luck!
