I'm getting married in the morning!!! But...

My bridesmaids invited people over to my hotel room to get ready with us!  There are some girls coming to my sma wedding who are not standing up in it (their boyfriends are that's why they're invited) and my bridesmaids invited 2 extra girls to come to my hotel room and get ready with us. It was a kind gesture but not one that they ran by me and the hotel room is not big enough for 6 full grown women to get ready in not to mention I was looking forward to getting ready just me and my girls.. Was this rude of them to do without asking me first? And what do I do if these girls show up tomorrow?
