Up to two children ages 2-12 are eligible to receive a 50% discount with each full fare-paying adult (age 18+). If any additional child per adult will be traveling, reservations must be made for that child as an "Adult" and the full adult fare will be charged. One child (classified as an "infant") under the age of two may ride free with each full fare-paying adult (age 18+). Infants are not entitled to a seat. Additional children under age two are permitted with each adult traveler under the 50% discount policy.
