For us we have 3 grandchildren ages 6, 4, & 1 all of their 1st birthdays were celebrated at WDW. We chose the monorail hotels for the simple fact that when they got tired and just need time away we could jump on the monorail and be at our room quickly. Our home resort is BLT so there are times we could just walk to our resort. Convenience of the monorail is hard to beat but it does come at a premium.
AKL - Kidani we have not taken the GC there yet but it is on the list as the pool activity area there IMHO for children would be hard to beat.
BLT - Monorail and is very nice
VGF - Monorail but other than that we did not enjoy our stay here in fact it is off our list.
POL- Monorail our favorite hotel
All-Stars were fun for our kids
To those who say the children don't remember it I will say that has not been our experience ours actually talk about specific rides and one talks about the kiss he got from Cinderella he literally floated away on that one.
No bad choices here its Disney World have a magical day.
