If this is the wrong spot, forgive me. This site is beyond overwhelming!
I just booked a trip for the last week of February 2015 and now I'm panicking! Did I choose a week where it's going to be crowded? Raining? Did I choose the right hotel?
How do I check for events that are going to be happening that week? Can anyone talk me down?
If you're set on February, the last week is probably the best.
You'll be missing both Valentine's and President's day massive crowds.
These are the things I believe will/may be happening at the end of February and first of March....

Disney Diva's 8th annual trip

Spring Dapper Days event

Plus Cheer Camp competitions

I don't have a link to their information.
I'm booked for March 4th through 7th. I'm expecting it to be BUSY... Being tied to school schedules doesn't give any flexibility.
We will go and have a fine time!! The grandkids are already planning which rides they want to hit first. So far only my 10DGD and 12DGS are going with me. However, if it's like other times, as it gets closer the other two (20DGS and 16DGD) may decide to join use too. I say the more the merrier!
We're coming from the PacificNW, SoCal weather will be better than we are experiencing in Feb/March. So I'll be fine with whatever we get.
Which hotel will you be staying in?
We chose one on Harbor, for easy access to and from the parks.
If you can find a "zone of time" where there will NOT be crowds, please feel free to share your info with all of us. We're all looking for the slow times we remember from the past.
I say STOP panicking and start PLANNING. You're going to have a fun time and the weather is going to be GREAT!
