We've always done evenings and never mornings. And, it's worked out well. We can walk on any ride. However, this last trip we decided to try MK morning. The wait for Space Mountain was at its longest at that time of day. They don't open all of the park, just Fantasyland and Tomorrowland. So, it was very congested. Not a good choice.
And, this past trip, we found that evenings were no better. Horribly busy.
