How would you feel about the following message being included with a school-aged child's birthday party invitiation?

"You may choose to stay, but are welcome to drop your child off for the duration of the party. Siblings are welcome to come, but will only be able to participate if space is available. (I expect there to be a few sibling slots, but won’t know until party day.) Each participating child will receive a chicken nugget lunch box. Light bites and party sweets will be available to all. Your presence is the greatest gift; presents are optional."​Helpful and make you more likely to attend.Too much info and make you less likely to attend.Neutral or you wouldn't care at all.Some other response. Please feel free to elaborate on your opinion or offer changes to the wording as well.​Thanks so much for your help.​Edits to original post below ----------------------------------------------------------------------​Many are commenting about the sibling wording, so I am going to further clarify to see if someone has better wording:The point I'm trying to make is that anyone is welcome to come and be present. However, it's at a place that has a program so the parents and siblings will be in the viewing area because they cap the number of kids. I do plan on getting a head count, but I can't promise siblings a spot in the program until I get all the RSVPs in. They are welcome to come and I'd like them all to be able to participate and go back with the kids if they can, but I can't guarantee it. The point is to prevent parents from having to worry about childcare for siblings.​Thank you all so much for the helpful feedback. I really appreciate it! via /r/Parenting https://ift.tt/2WAMcid
