When bringing a wagon and then you ride the train is there somewhere to leave your wagon

yep, a stroller parking spot thats monitored. i wouldnt reccomend a wagon though, theyre annoying, too large when its busy. so your answer would be yes but it might stick out

Honestly I don't remember... I did see plenty of wagons and I did ride the train which I highly recommend. If it's warm wear comfortable clothes something to try to stay cool with because it does get warm. There are funny places to rest in the shade and to get food and drinks be ready to walk LOL
