Am I unreasonable?

My husband and I are having our first child. Both our families are super excited. Now I know most people have a shower thrown for them trust me I’ve already had an ear full, however I’m planning the shower. I really want our guest to come and just enjoy the party & if I’m being completely honest it’s hard for me to have other people help because I’m very particular on how I want things done. I completely understand that our families want to help and are excited but I really just want it done my way. Am I being unreasonable? Planning the shower isn’t stressful to me at all, but when other people get involved it definitely does make me stressed. Maybe I’m just a control freak idk. Thought?
