So, diving a bit into the numbers and using JD's date of October 13 (and 14 for this year to stay on a Monday). Looks like for multi day tickets, the increase is around 7% on tickets. Largest increase is on a 3 day ticket at 7.78% increase, while the smallest increase is 6.45% on a 10 day ticket.
Interestingly, park hopper tickets are what have seen a larger increase. Overall, it's 7.60%, but much more skewed towards the under 5 day trips. 2 day park hoppers went up $63 (a 15.89% increase). 3 day park hoppers jump almost $68 for a 10.32% increase. So to me, they are really pushing to not have people hop at all (probably has to do with keeping minimum staff throughout the day).
