[Edit]Just found out 12/6 was sold out. But otherwise the following stands regarding my experiences overall.
Went to the 12/6 party and I definitely saw marked difference in crowds than 12/3, the latter of which was sold out. Still crowded, but a lot of people seem to stake out the hub for the shows. Seems a lot more manageable on a non-sold out party. I had the Tony's extra, but really didn't feel necessary today as I saw plenty of space around the vip area. I don't feel like I could say the same for the 12/3 party as my dad and I caught the tail end of that after meeting Moana. And that area was jammed.
We took it really easy tonight (even more than the sold out night) so it wasn't efficient but it was still fun.
Christmas Party items we did:
Castle Lighting (6:15).
Met Snow, Aurora, & their Princes
Grabbed a gingerbread sundae
Hit Space Mountain (loved the new overlay)
Watched Edge Effect
Collected our SotMK card
Went to Tony's
Watched parade
I think the Tony's party is worth it if you drink and don't mind a more easy going touring of the park during the party. That said I am really glad I experience two different
MVMCP's
I can definitely see why people complain but on the other hand, I can see myself navigating a sold out party relatively easily now. Glad I did the extra extras (dessert party first night & Tony's second). I probably won't get these again but I felt they were good as a one time thing on top of MVMCP if you can afford it. Takes a lot of pressure off the decision of what to do if the party is sold out/ want to get spots to view the parade/fireworks on Main Street.
These were my first two MVMCP and I am very satisfied with both experiences. Whenever I get back for the holiday season, I will definitely have this on my docket (or at least in consideration).
