Hi Mep...
I am almost positive the 5th floor rooms are all deluxe savanna view.. and floors 2, 3 & 4 have standard savanna view.
The deluxe rooms are 'slightly' larger than the standard.. maybe 50 square feet, nothing noticible. They have a makeup mirror and robes and some rooms have a daybed in addition to the other bedding.
Many guests swear the 'animal' viewing is better from the lower floors ~ and after staying on the 5th floor twice, I can understand what they mean... you really do get a better look at the animals up close.
On 5 you get a better view of the whole savanna and resort. You may love your first room and not want to move, who knows?
The rooms used for concierge are close to the lobby so you are not trekking forever to get to the lounge.
I think if I were you I would discuss the options with concierge one you have arrived in your first room. See what they planed to assign you and decide then what you want to do.
Is concierge sold out for your first few nights or are you splitting on purpose?
Have Fun
