I have already gone to several parties and camping for a whole weekend with Ahi. I bring all her basic necessities and her crate and playpen. The people i'm around are very good with my no touching policy. I do let them touch her if they sanitize.(And depends who it is.lol) But my baby loves kids. When we were camping I put her crate in the playpen and she could go inside her crate if she wanted to rest. She is really tiny too at 10 1/2 weeks she's only 1lb. 1oz. so I do get worried at too much carrying esp. from a child. But the playpen is a life saver for me. My Ahi didn't get sick when we went camping,(and it was regular hardcore camping..no cabins) I just used common sense with the weather. And I think it helped with getting her used to the sights, sounds, and multitude of people. I hope you get to enjoy this party.
Just my thoughts.
