I wouldn't pay $119 for it, but we're APs so $89 is more palatable.
We did
MVMCP a couple of years ago. We too are AP. My thoughts:
1) It is a lot of money for a few hours and some free cookies and drinks
2) When we did the event, we were meeting up with people that were only doing the event, and not purchasing a ticket for the day.
3) For that event, I believe you could get in at 4:00 PM, and the park was the open until midnight (basically 8 hours vs. 6)
4) Since we're an AP, this was really my only ticket cost for that trip, and it was just my wife and I.
No having said that, last week, we arrived at MK at 8:30 PM, and my kids and our friends kids ran around and were able to ride 5 big rides in 90 minutes until closing. The only FP was 7DMT at the start. My point being there are times that you can run around and not wait on lines and not pay for an extra event.
Having said all of that, my vote, you have to try it once to see if it is worth it for you or not.
