Which resort is best for our family of 4 with two boys ages 2 and 4? We want to spend a good chunck of time at the pool and I think my boys would really enjoy the kiddie area at the beach club (the small slide looks pretty cool!) and it seems like it would give us a chance to sit nearby and watch them play, as opposed to the larger zero entry pool at the poly where I expect we would need to watch them more closely. But the monorail access also seems key, as my kids wil probably want to keep returning to the magic kingdom. Is the poly pool ok for kids this age? Should I spilt time between the 2 hotels, even though we're only going for 5 nights? Thanks for your input!
