Would it be less crowded on a weekday or weekend in May/June? I am thinking during the week there may be a lot of school trips. Any tips?

I know someone mentioned bringing a wagon - is this really allowed? Are there areas to park like in WDW? We plan on riding the monorail, etc. Would it just be easier to bring our Volo and let the kids trade off (they are 3.75 & 5.5)? Or try and brave it w/o a stroller? Can you bring food and/or drinks?

Any advice appreciated. I have never been to a big zoo before so I hvae no idea what to expect!
