We ordered last minute so there were no delivery times available on our arrival day but we had no problems with our order or delivery.
Best choice we made..This site made it easy to not worry about the expense of water in the partks as well as I did not need to add weight to my luggage by packing diapers for my son. Will use again on my next trip to Disney :)
So easy and friendly to use. Email responses to questions were same day and phone operators were very helpful!
