It's been forever since I've been, but we're going this weekend with two toddlers (niece & son). Would you recommend taking strollers or a wagon? The wagon would be nice b/c they could entertain each other & my son is going through an anti-stroller phase with his newfound mobility, but I didn't know if a wagon would be too much of a PITA to pull around with a lot of people there. Thoughts?
