I do want to point out the funny thing about people saying there are too many people....we aren't even filling up the park
Like they could fit in another 3-5 thousand guests into
Disneyland still. Indy and Space used to get 3 hour waits
I will say what I've noticed recently is less CMs, not like a huge amount missing but less people doing the photo pass with characters and a few less for crowd control. Maybe I am imaging things but that feels like what I've noticed this holiday season
I will also say the best bet is to rope drop and hit rides until the crowds are too much and then go see shows as you get more LL ready to go. DCA has a lots of shows and many of which aren't filling up and this isn't due to lack of people in the parks but people just not going to watch the musical shows in Hollywoodland at nighttime, every time I've gone to those they have 1/5 the amount of people they could fill
So for many they just want rides and cool but your going to have a worst time trying to get on rides right now, if you want a full day I'd watch the Dapper Dans holiday show, Deadpool, The Encanto show/Disney ¡Viva Navidad! Street Party and also mobile order food.
I've gone 3 all day trips this season and yes, rides wise its not the best (but I will say the rope drop hour and last hour are both still really good). Like I did an all day trip and did 39 Rides and shows.....on a weekday day
