No Disapalooza this year............its Podcast Cruise 6.0. I believe they do it every other year. We were at last years event at Universal and it was awesome. Expect to see it come back in 2017.........I hope.
Yes, there has generally been an in-Park event every other December, alternating with a December cruise. This year's December event is a cruise on Royal Caribbean's Oasis of the Seas Dec 4-11. Podcast Cruise 6.0!!!
I'm pretty sure there is still space available- check out the Podcast Cruise 6.0 thread stuck at the top of the forum and consider sailing along!!
