Thank you.. these comments help alot. I also had expressed im nervous about putting my 5 year old in a room with 2 boys he doesnt even know..He had also said he feels you just throw the kids in a room and let them figure out and the adjoining door is right there.. I just disagreed. And thing is we DO have our own trip planned 2 weeks prior. alone for 3 days. He said he felt unwanted and dictated to.. I said i feel the kids come first in this situation as this is first meeting of everyone together.. that opened a whole can of worms as he said he feels the kids DONT come first.. that comment has really effected me and still does. I get you need to make a partner a priority but this is first time family coming together.. Im so torn. I need to bring it up again as need to book trip.. Thank you for all the feedback.
