#1 VWL b/c when they were that little we went to MK more times than any other park, kids loved the pool & geyser, access to the beach to watch the Electrical Lights Water Parade/watch MK fireworks (while waiting they could play at the playground or in the sand, stroller on & off boats, VWL seems likes the resort which is closest to the bus stop, counter food close to the pool, & sit down restaurant Whispering Canyon is family friendly w/ Lincoln Logs, pony races led by the servers, etc. And they have a kids club on site if you want to enjoy a more adult meal at a fantastic restaurant whose name escapes me this early.
#2 AKL for the animals, great pool, wonderful free kids activities around the pool area, storytelling around the fire at night, great counter service, & my kids enjoyed Boma's buffet--some kids don't enjoy trying new foods. My toddler at that time loved quinoa & pap ???, cookie decorating, so much to see & learn just from walking around the resort. My then 5 yr old never stopped talking about getting to try the night vision binocular w/ one of the CMs, great kids club & wonderful more adult restaurant w/ fantastic South African wines at Jiko. If you stay Concierge on the right days you can pay extra for a early morning family safari before the park opens that is like no other & ends w/ a fantastic breakfast buffet in the park w/ the guide.
#3 BCV for the pool, location, Cape May character breakfast, easy access to counter service--including Beaches & Cream for yummy ice cream.
We own at BWV, but have only stayed there twice, b/c DH's fav is AKL & mine is VWL.
My kids are older now enjoy the ESPN zone when we stay at BWV.
Have a great trip!
