I'll put down a few thoughts for you. Would I go back to Elephant Watch? You bet. However, it is very expensive as you state, and now that I'm retired I have to watch cost. I can no longer justify $650.00 a night for sleeping in a tent - regardless of how fancily it is decorated. A tent is a tent. The positive is IF Iain and Oria are in camp you can learn so much from their years of elephant study. Even though my favorite guides are no longer there, I'm sure they have trained equally good people to take over.
I'm sure all Oria's guides know the elephants better than guides from other lodges/camps. Due to Iain's work collaring, all the men know all the Samburu elephant families and each member of the family, and the elephants know them and their vehicle well also. When I was there EWC guides got much closer to the elephants than other vehicles I saw.
Is the game watching in Samburu better than anywhere else? That is a hard question for me. As you may know, I'm an elephant lover so seeing them is most important for me. I try to go where I'll see the most elephants. I must admit that Samburu is the only place I've seen leopards, so if that is important for you then Samburu is a must for you. It is also the only place I've seen giraffe "necking". Twice when in Samburu there were tons of animals. On one trip there were very few animals in the reserve.
I personally prefer Amboseli and Tsavo East National Park. In Amboseli I've been able to go out on game drives with the elephant researchers and you get REALLY up close to some of the Ambo elephant families when with the researchers. They are the only ones allowed to drive off road and will go right into the iddle of the elephant herds. In Tsavo East at Satao Camp in the dry season there were literally hundreds of elephants at the waterhole in front of my tent day and night. However, with Tsavo being so huge, you have to travel farther and look harder to see many of the other species.
You must remember that what you see depends entirely on the weather. During the dry season you'll see much more than you would during or just after the rains when food and water are plentiful everywhere.
I always plan my trips for the dry season for that reason. In fact I'm returning to Kenya leaving here January 31st and will stay a full two weeks at Satao Camp in Tsavo East where hopefully, if they don't have late rains, I'll again see hundreds of eles. from my veranda (some of them walking right past my tent).
It is wonderful watching the reactions of the elephants, hippos, buffalo sometimes, giraffe, lions, zebra, waterbuck, impalas, kongoni, baboons and monkeys right from your veranda. Usually at Satao I don't even go on game drives. Why ride for hours looking for wildlife when it is right in front of your tent?!
To get back to EWC, if you can afford it, it would be great to do. If you're taking cost into it, I think you would have an equally good experience at Serena or even Samburu Lodge. If you are just thinking about seeing wildlife in a tented camp anywhere, then I'd think of Tsavo East and Satao Camp. It is my favorite place. I've referred a few people to Satao and they all love it as much as I do.
