L.C.
We haven't done the Pumpkinliners trip in Fillmore but we have done the Thomas Trip and the trip to the Fish Hatchery in Fillmore. Pumpkinliners is probably similar. You're only on the train for a short time then do whatever activities they have.
I do think their trips are a little expensive. The kids really enjoyed the trips but my husband, my mother and I thought they weren't worth it - Thomas was a complete waste of money - but the Fish Hatchery was educational and they got to feed the fish. That being said, if the weather is nice, it's a nice drive to Fillmore and a nice day trip for the kids - something different to do.
I hope this helps...I guess it's worth checking out once to see if you like it... Have fun!
