We are heading out for our annual WDW trip in 2 weeks. We have taken our twin girls before 2 times but they were 3.5 the first time and 4.5 the second. We are now traveling with our 3 children our youngest being 16 months old and our daughters are 6. Any tips on visiting WDW with a young child would be greatly appreciated. Luckily we are staying at the Bay Lake Tower for easy access to the Magic Kingdom. Thanks so much!!
