I get this all the time. Ironically I end up with everyone saying how awesome it is minus my family which completely sucks. My family is extremely close so it makes it difficult that they aren't into the idea of a DW. My dad doesn't believe you should get married anywhere other than where you grew up. I basically don't share wedding details with my family which is hard and upsetting, but I'm just planning it and they can gripe all they want but when it comes down to it, they better show up and shut-up and have some fun!
Then on the other hand FI's family gets super excited about the idea of a DW and we weren't planning on inviting them at all, just to the AHR. So now our ideal intimate wedding of no more than 25 is now more like 75!!! When it comes down to it in the end it is your decision and you will do what you want. If people don't want to go then they shouldn't go.
