I've never been to the S/D, but i've seen tons of pictures and have heard great reviews on the hotel.
This is the way i see it, the S/D are great hotels with nice regular hotel theme-ing. AKL on the other hand, is like visiting an African-style lodge with authentic food, arts & crafts and animals. How many activities does S/D offer vs. AKL?
There's no way, IMO, to evenly compare both resorts unless the price difference sways you that much. I'd pick AKL at $225.00 a night over any other hotel at the same or lower rate; even if a MOD was priced at under $100.00 (no way w/o a heck of a discount or pricing error), i'd still pick AKL; the resort is that nice, at least that's the way we feel about it.
