Disneyland March 5-8 looks packed out via hotel bookings; is this a bad time to go?

Hi folks! My wife and I are looking at going to Disneyland March 5-8 as we’ve seen on a few crowd predictor websites that it should be a decent time to go. However, we’ve noticed that the hotels are SO expensive compared to the week before and week after. Is this because of the big Expo? We just don’t want to waste our vacation if it’s going to be ridiculously packed.

I know it’s impossible to predict, but for those of you with more experience going throughout the year, is this still be a good time to go or should we reschedule?

Thanks!
