We are throwing a joint 2/4 year old party for our kiddos at a gymnastics place. 1 hour class for the kids led by the staff, then cupcakes after.

I am not a fan of party favors personally, but I am wondering if others will be expecting them? We are trying to keep this pretty low key, but this is the first time I have invited kids we don't know (we are inviting kids from my oldest's class).

Also, at this type of party, should I tell parents they can feel free to drop off their 3/4 year old and come back? Or would that sound like I am trying to get rid of people? I don't mind if they stay, of course, but at some point parents don't stick around anymore..right?
