This decision has to be YOUR decision, not anyone else's. Just like when other people plan their weddings, they don't talk to everyone first and find out what they all would prefer. Its your wedding, your choice. You will never find somewhere that makes everyone happy, its just how it is. If its really important that your one friend be there and that your dad and step mom be there, then you might need to reevaluate your decision, but if thats not a huge factor, then stick with where you are. Just make sure wherever you book, it is where the people that you want there, will be there.
