Unfortunately, you cannot add Disney After Hours (including BOO BASH and Very Merriest) to a Personalized Touring Plan. Fortunately, if you attend this separately ticketed event, you will find lines to be very short. In fact, we've found that the lines for the "free" ice cream and drinks are often longer than the lines for most attractions!
For the most part, you can tour land-by-land, riding whatever you want when you come to it. Popular attractions (like Seven Dwarfs Mine Train at Magic Kingdom) can be an exception to this, but even if the attractions are not "walk-ons", their waits will be much lower than during the day.
At this time, the only "extra" Walt Disney World hours supported in a Personalized Touring Plan are those associated with the following:
- Early Theme Park Entry
- Extended Evening Theme Park Hours
- Mickey's Not-So-Scary Halloween Party (last offered in 2019)
- Mickey's Very Merry Christmas Party (last offered in 2019)
