Actually, that is probably an individual preference. For the family that has just one or two days at the park or due to work or personal reasons cannot plan a vacation 60+ days in advance, the paper system was possibly more fair to them. Additionally, for anyone technically challenged with smart phones or PCs, obviously the paper system would be easier.
For others there is a certain sense of security knowing that in 60 days, their family will show up at one of the parks and be guaranteed at least 3 attractions that do not involve an insane wait in the standby lines.
