We went on Mother's day the year before last, and I didn't think it was bad at all as far as crowds go. We have always gone during "slow" when there were no crowds, so that is what I was used to. I had heard that Mother's Day was really busy , so I was bracing myself for it to be really crowded and it wasn't IMO. The following weekdays were actually much worse as a lot of schools, youth groups were there on outings. I was amazed at the lines stretching across the esplanade on Tuesday when we arrived.....Yikes! I loved being there on Mother's Day and would go again if I could. They have tables with carnations on them for all the Moms when they enter, so that is a really nice touch too!
