Just did sold out magic kingdom yesterday. Was able to LL Space, buzz, Pooh, tea cups, mermaid, pan, haunted mansion, big thunder, pirates, and jungle cruise in my 12.5 hours there. Averaged a FP redemption every 75 minutes. Also had time to ride standby on people mover, monsters Inc, tea cups, big thunder, splash, pirates, and watched fireworks!
No early entry. I would say G+ was for sure worth it for my family, longest wait of the day other than fireworks was 30 mins for splash. Hit the 120 min rule only twice!
