We're also going, March 30-April 7, which is spring break for some (but not all) Minnesota school districts. I am expecting it to be busier than when we went President's Day week three years ago, but it also looks like the weather should be warmer so we will be happy to leave the parks for the pool in the afternoon. Regardless, I think we're better off than those going over the following two weeks due to Easter. I didn't have my dining reservations completely finalized until a few weeks ago (and I hadn't even started making them until late December) and I didn't have any trouble getting anything I wanted, so I'm hoping that's a good sign. Have fun!
