We have taken several trips with toddlers the past few years. We spend a lot of time at the pool. Based on our experience I would review them this way:
Kidani splash area is awesome for a 1yo. Plus there is a zero entry pool and a tiny water slide, great overall pool for a toddler.
SSR has two fantastic pools for toddlers. The new paddock pool is AWESOME for little ones. My 1 and 4yo loved spending the afternoon there last Fall. The splash area there is easy and safe for little ones to climb on and the little water slides are a lot of fun for them. Plus an adult can go down those slides with toddlers on their laps easily and safely. I did it about 50 times, lol. Both the paddock pool and the main pool at SSR have a zero entry too. The Donald splash area at the main pool is small but my kids loved it.
OKW is fun because it has a sandy beach area, but the pool isn't zero entry and there is no small slide.
BWV is tougher with a toddler without a zero entry and there isn't a splash area either.
WLV was fun, but I wouldn't pick it first for a 1yo (no zero entry, no splash area)
My vote would be SSR first and AKV second based on pools. We haven't tried SAB at BCV yet, I have been nervous about keeping an eye on my little ones at a pool so big (they are 7, 4 and 1).
We haven't tried BLT either, the pool looks fun for toddlers but it looks so much smaller than either AKV or SSR!
