Other than Saturday and Sunday (Dec 11 and 12), I thought the crowds were about the same as last year. We were there all week Dec 5-12 and did not have to wait long for anything. In fact, most rides were walk on.
Monday we were at Epcot, Walk on to MS, did twice in a row. TT we had a wait due to the ride being down, but the wait was less than 15 min and then we went back on it again.
Tuesday we were at MK, did the KTTK tour (it's great), no waits for any rides (did HM and POTC - our boat got stuck, that is another story) after the tour did Buzz and SM twice with no waits, then on to the
MVMCP. Did twas the night before xmas and ALL rides were walk on, in fact did Splash 4 times without getting out of the log. Saw Wishes from near caseys and the second parade from Main St, only needed to stake out a spot about 15 min before.
Wednesday was MGM, again walk on to TOT and RNR. Did both twice, most shows were mid sized crowds. Did the FDP at the Brown Derby . It's not quite my kind of food, but it was still good (isn't the Cobb Salad great) and got great seats 6 rows up for Fantasmic (and only got to Oscars 20 minutes before the start)
Thursday was an EE day for MK and we had a PS at CRT for breakfast, 8:10, no waiting, just checked in and walked right up to the dining room. The Princesses spent a lot of time with DD (23). This was for her and she couldn't have been more excited. Again back in the park with little lines and waiting. Peter Pan, Snow White, Pooh and Dumbo were walk on or 5 minute waits. In the PM, over to AK, All rides were walk on and had no problem getting a good parade spot at parade start.
Friday Back to AK for FOTLK and rerides of everything, and the trails. Did not see Tarzan Rocks only because of our timing. Everything was minimal waits.
Saturday was the only day that we had waits and we were at MK most of the day Splash was 30 minutes and we fastpassed BTMRR as it was a 60 minute wait. Fast passed Buzz, waited 30 minutes for SM. Saw Stich earlier in the week (don't waste your time, it was not a great attraction - I expect MUCH better out of Disney)
As you can see, thee were no significant crowds during the first week of Dec and we were even at MK on an EE day. Even with Pop Warner and the Cheerleaders, we would come back again at this time of year. It may be getting busier, but still is not bad at all.
