Yes, I figure Jan-June will be busier because of all the AVOID Star Wars at all cost crowds. Easter is an interesting idea. I typically avoid Easter because of the historic crowds that day/week.
We found spring break time this year to be insane and I vowed never to go during spring break again (which is basically March/April).
We're OK with refurbs. Seems there's always something down anyway. We go often enough that we don't feel like we miss much.
We need to be in SoCal for some family stuff, so I was trying to plan around a day or two at
Disneyland. I'm thinking we won't stay on property this trip, and book somewhere in OC for a beach trip.
