Hi you cannot reserve a seat and about 3-4 people per seat with 6-10 train cars per train. You get in line to sign a waiver then get in line for the ride. Dad stood in line then called us from the play area when our turn was getting close. It seems to run 12 months a year.
I believe someone answered your question but the best thing to do would be go to the park website
Yes the train run all year and you sign up on the day in front of the station yes for parties the train can be rented for a price it's on there website for rentals
