For as long as she stayed awake, that is! She loved WDW, and started getting excited and bopping all around on the bus on the way to the party. We had taken it easy that day, eating dinner in the food court before heading out to the party. Since she had expelled so much energy on the bus, she passed out soon after we arrived at the party. DH wanted to leave right away, but since DD was sleeping so soundly in the stroller (remember to bring a reclining stroller with a big shade), I was able to convince him to stay. We brought her on all the rides with us, and she slept through them. I wouldn't have done this if I didn't already find out this worked all week long, since she took two naps daily. Anyway, she woke up cheerfully later in the evening, and enjoyed the rest of the party with us! I hope this will work for us this year, as she will have just turned 3, and can stay up late with little problems.
