My personal gripe isn't with Trick o' Treat Town (same acronym as Terror of the Towers.. very confusing!) in of itself as it was actually more enjoyable than half of the mazes this year for me, but with just having another upcharge attraction on top of the already existing ones makes me grumble a little, as I feel I'm already paying out loads.
Although I would expect there are a lot of people who would do the scary mazes but have no interest in trick o treat town, likewise many people with kids doing tot town but won't do the scare mazes as they have children.
Maybe yes there could be more included, but there does appear to be slightly more roaming entertainment this year and a variety of stuff on the main stage. I think maybe they could have done one smaller second stage in Fountain Square again and spread out the entertainment a little more similar to Oktoberfest having two stages.
Some parks of course don't offer any Halloween stuff in the regular park price and it is all additional costs. Disney decorate the park but all the entertainment is only at the upcharge separate party event.
