Great topic!
Off the top of my head:
1) Wolwedans Mountain View Suite - Super private, 200 square meters with an expansive deck, and sweeping views of the amazing desert surroundings. It's incredible. Check it out
here:
2) (tie) Mara Plains Camp (Family Suite) / Mombo Camp
Among the top safari lodges that we've stayed at, these two have the best views of a variety of wildlife from the room. Elephants, Hyenas, and even Lions at times. I can sit outside on the deck all day. Mombo has newer and fresher rooms, and I prefer its decor, but Mara Plains has a family suite that has all kinds of space, and has slightly better wildlife sightings right from the room. Zarafa Camp, with its 2BR Dhow Suite, would also be an option here. Choices, choices.
3) Amanpulo - one of the Villas, please.
