Even if it is "only" one hour, let's look at the MK per hour cost increase between equivalent days in Apr 2015 and Apr 2016, taking into account both the one hour decrease and the increase in ticket price:
Thursday Apr 30, 2015
One day MK ticket = $111.83
Hours 9am-11pm, or 14 hours
$7.99/hour
Thursday Apr 28, 2016
One day MK ticket (regular season) = $117.15
Hours 9am-10pm or 13 hours
$9.01/hour
Or an
increase of 12.8% per hour from 2015 to 2016
Think it gets better with multiple days? Nope.
Thursday, Apr 30, 2015
10 day MYW $388.73 or $38.87/day
Hours 9am-11pm, or 14 hours
$2.78/hour
Thursday, Apr 28, 2016
10 day MYW $426.00 or $42.60/day
Hours 9am-10pm, or 13 hours
$3.28/hour
