We offer a standby policy for participants who would like to join us for individual trip(s). Please note that every bus is over sold by 4 seats, so space is not a guarantee. We will not know if we have space until all paid participants and chaperones have boarded the buses. This is a first come first served situation. We have never had to turn someone away, however this has become a popular option. We will continue to offer this option until we find it to be a hassle.
