We just returned from the world today after our trip from 2-1 thru today. I must agree OP, it was so BUSY!!!
We have gone in feb several times, usually this week or next. We have been to disney yearly for 14 years, so we aren't experts, but definitely know the in's and out's.
We stayed at Pop Century and thought i would kill someone by the end of today. Now I must say the only times i noticed the BTG's and the cheer/dance craziness was meal times, bus lines and the crowds that would head to a ride (60 people at a time) and shove you out so you couldn't get away! It was annoying to have them on all sides and not be able to hear yourself think! They were very loud! And more then once I saw others getting angry. At one point two grown adults started actually fighting in the bus line! (poor families!) The man had had enough, and the straw broke his back when the ENTIRE group in line, went under the rails in the bus line and his family missed the bus! They came running out of nowhere! It was a sight to see, and became a very good teaching moment, as we all "looked at...(insert random insect, lizard on tree, bug... anything to be distracted from the adults) !
The crowds were HORRIBLE at MK. We do that park in 1 1/2 -2 days every trip, so again, know how to utilize our FP, and such... Even with that, we barely touched the majority of rides
Fantasyland was CRAZY! no ride times under 45 mins, even during the parade!
But I must say, even with all that, it was a fun trip!
And now I will go back to going in the fall, and pray for no large groups of any kind!
