First of all, congrats on your engagement! I think most of us on here have gone through this stage of others grumbling about our choice, and most of us have decided to ignore it and do what we want to do! It is YOUR wedding, so you have to decide what feels right. If you can't imagine having a big wedding at home, then have a DW. If you decide that you won't be happy unless your are surrounded by your entire family and all of your friends, then maybe a DW isn't right for you. Whichever you decide, do what feels right. Good luck!
