what is a better restaurant to eat at if you want to view animals after and wander the resort?? Sorry to jump in here
It really depends on you. Jiko is a Signature and is far and away the best of the three, IMO. However, it is a quiet and more romantic and may not be the best restaurant for the little ones (of course you could feed the kids at The Mara, which is a nice CS, while you and your DH have a nice romantic quiet meal without them, and then pick them up after your meal to wonder around a bit).
Sanaa is at Kidani and has a really nice viewing area with a much better firepit than Jambo (again, IMO) really close to the restaurant, which most people go to while waiting for their table. Also, if you are eating durring daylight hours, you could be lucky enough to sit at a table that faces the savannah. We really enjoy Sanaa, but the food is not for everyone.
Boma is the safe choice, seeing as it is a buffet. It's one of the few buffets that I don't mind paying OOP for. You could get your moneys worth on soups alone. The dessert offerings are pretty good too (personally, we don't LOVE Zebra Domes the way some people do, but they are decent and are part of the buffet). While the food is good, my favorite thing about Boma is the way the smell of the wood grill/smoker makes the resort smell late morning.
All the restaurants are pretty much in the middle of the resort (Jiko and Boma are 20 feet from eachother, if that) which makes it pretty easy to wonder around.
OP, if it came down to upgrading to a savannah view or going on the Wanyama, without hesitation I would choose the Wanyama. We did this in October on our first night (moments after I proposed) and it was without a doubt one of the best experiences in all of WDW. First, you go on a guided tour of the savannahs. There is only a max of 12 people allowed per night (and you must be 8+, unless you rent out the whole safari for your party). The guide talks about the different animals and how they are cared for, etc. etc. etc. You really get up close out there (a giraffe stuck it's head into our safari vehicle, to give you an idea), not to mention you can get some great shots of the resort from an angle not everyone gets to see.
After about an hour and a half or so in the savannahs you get an amazing feast at Jiko. Bread service, a few appitizers and a few entrees are all served family style to the table and a trio of desserts are served individually. Wine pairings are included in the price. The chef will come out and talk about each of the dishes and the service is top notch and quick with a refill of wine, soda, water and coffee. To us, $190 (which includes tax and tip) is almost a steal for the experience. The guests we took the safari with were really nice and friendly and we all really had a great time.
The only thing I will add is that I highly suggest doing it early in your trip, this way you can apply some of the things you learn about the animals to when you view them through out your trip, but don't book it for your first night. I lost a ton of sleep in the 180 days leading up to the trip, fearing that something would happen that would cause us to miss the safari and being out $380. I was actually more nervous about that than proposing. In any case, AKL is an amazing resort and no matter which way you go, you'll have an amazing time.
