Needing some guidance from some seasoned pros...will be visiting SW on either March 11th or 12th (Wed/Thurs). Any idea on what we can expect in the way of crowds on these days? We'll be doing SW one day and US/IOA the other. Also, will we be able to take a stroller in for our two year old? I'm assuming it's not an issue, as we were able to take it into BG a couple of years ago. Can't wait to get there! Long overdue vaca for everyone! Always looking for any veteran advice as well!
