We are having my daughters 2nd birthday party at the end of June.  We are inviting aproximately 50 people ranging from family members, friends, to kids and their parents from her daycare (some of which we don't know that well).  To avoid chaos and boredom from some, we were thinking about not opening presents at the party...what do you guys think?  Personally, I would like to have her open her presents, but with so many people and so many fun things to do, we are thinking of saving the opening for after the party. 

 Any advice is appreciated :)  Thanks!
