My husband was given 2 one day, single park tickets a year ago to Universal or Islands of Adventure. We were planning a trip already for this November, and could not swing an extra trip. We gave them to my niece to use - supposedly in May...then June...then July. She finally said no, they couldn't go. They expire July 17. Can anyone guide me to the best place that I could get them sold for a fair price? TIA!
