Roger Williams Park Zoo has different admission rules for the final two nights of its Jack-O-Lantern Spectacular: regular Saturday, Oct. 31, tickets and a 21-and-older Last Call event on Sunday, Nov. 1.

The Great Pun-Kin Trail uses carved pumpkins and visual wordplay drawn from pop culture and familiar characters. The zoo says the trail includes more than 5,000 illuminated pumpkins.

The regular event page lists Saturday admission at $23 for adults and $19 for children ages 2-12, with children 1 and younger admitted free. Tickets must be bought online in advance. The listed evening hours are 6-10:30 p.m.

The separate Last Call listing is for ages 21 and older on Sunday, Nov. 1, from 6 to 10 p.m. Admission is $30, with live music, fire pits and an optional buffet add-on.

Visitors should choose the ticket for the correct dated event. The zoo's main event page says tickets are nonrefundable and cannot be rescheduled.
