And I just did the night safari Sunday. I thought with the Superbowl going we might get a tour to ourselves but no, we had a truck of 10 so no personalized requests. The truck stayed mostly in the Sunset savanna. Not much got close, in fact if something looked like it was heading towards us the truck would drive forward. And we were being so good with no flash but people on their balconies kept setting off their flashes that messed with what we could see. Yes the night scopes were cool, but you can borrow them for free from the Overlook. If you can't get the daytime Wanyama Safari it is a smaller, shorter version. Do I feel I got my $70 out of it? No not really, but I've been spoiled by the San Diego Zoo Safari Park's Caravan Safaris. ;-)
Boma, for breakfast you can probably walk-up. I had a 7:30AM ADR on Sat & the place was pretty empty. Of course as you get closer to park opening times more people come in. Dinner is usually pretty booked unless you get there right at 4 or later after 8pm. Sanaa, you might have a wait but it is less visited.
I didn't stay Concierge so don't know about the Lounge. But Mara was open late, got cup refills at 11:45pm.
