Disney will send security immediately if you call and tell them you have a lost child - HGVC acted like it was not big deal.....
well it was to the crying lost child.
so be sure to kept up with your little one. Always kept one eye on him at this resort. If you are in a 2-bedroom - make sure he knows how to get to your room - otherwise he might go outside the room.....
the bus transportation was not the greatest. you have to reserve it before you needed it - pay for it - then it was did not always show up when you had reserved it.
with a 2 1/2 year old I would definitely rent a car. She could easily get over steam rounded and have a melt down.... A car is a big assets when going to the parks with a little one.
