I loved the 5th floor with the pool view room. It is the top floor on the Giraffe Trail, so there is no one over you. Although the rooms are really well insulated for noise, In the past I've had a few jumpers over our room if you know what I mean. Anyway, We had rooms 5018, 5020, and 5022. You could see the Uzima savannah from our room, although it was on the other side of the pool. We saw giraffe, Kudu, cattle, and even bongo from our room. We've always tried for the savannah in the past but if you have to have pool view these room, and the ones furth down,ie. 5024,5026, 5028 and a few more further down seem to have the best views. If you like to be right by the pool of ourse you might want lower rooms but you can't walk right out from your balcony to the pool deck anyway, you have to use the interior corridor. There was an elevator near 5018(an end room) that took you right down to the pool so you didn't need to go to the lobby.
The pool view rooms on the zebra trail didn't have a view of the savannh, just the pool. You want to stay away from the second floor pool view rooms on the zebra trail, the one over Mara and the Arcade, their balconies have a half wall rather than an open fence so you can't see out.

Yes the Zebra Trail is great, Try to get rooms further out from the lobby. Either savannah from the zebra trail has great animal views. There were Tommys on the Uzima savannah that people on the zebra trail could see. The walk from the lobby is a bit much but the views are worth it. On the savannahs I'd try for a lower floor, since the trees are blocking some of the views from the higher floors.
The Kudu Trail on the Arusha savannah has great views but is further away from Mara. I wasn't fond of the Sunset savannah, although there were animals-great to see from the overlook- the actual savannah area wasn't pretty.
By the way there are giraffe on all the savannahs now(did't used to be) and the animals weren't in in the afternoons like they were a few years ago. Maybe it's because we weren't there in the summer.
