We purchased 2 day US/IOA park tickets that never expire back in March 2000. We were only able use 1 day back then. Now, 6 years later we are finally making it back! We are so excited, and will be staying at RPR April 18-20th. My question is, 2 of the tickets are Child since my kids were 9 and 5 years old at that time. Now they are 15, and 11. Will there be any problems in using these tickets for them? Also, my son's ticket had a problem scanning originally, and they had to scan it again. Did that count as using the 2 days on it? I hope not. I am so worried that we are going to get down there and our tickets won't be honored. Any help will be greatly appreciated. These boards are great sources of information. Thanks!
