The girls are right, it is your wedding and you need to do what you want, and just understand that some people may not be able to make the trip. I definitely know where you are coming from, and I often feel the same way. However, it's my parents I'm worried about. They don't have a lot of extra income right now due to a law-suit they are in against my uncle (long story, very messy). So my entire goal is to make it as affordable and accommodating to them. As for getting an idea of who will be going once we got engaged we announced that we wanted a DW and just asked the people on our guests list (there are only about 20) what are plans are and if they think they would be able to make it. Almost everyone is on board (except for most of my family) so we will go ahead and send our STD's to those and then wait for our final count. Like gossip girl said, by giving enough notice to those you want to travel they will have ample amount of time to save up. Hope it all works out, just remember to do what's most important to you and your FI for your special day.
