FH walking down the aisle before you Vs. him waiting at the alter

A little background… My FH has a twin sister and an older sister. Both of which are not in the wedding party which is OK with FH; I asked if he wanted them in it he said no, it’s OK if they’re not. Then a few weeks ago his mother and his aunt call him to insist (basically give him no choice) that his twin sister NEEDS to be in the bridal party (not his older sister mind you who he is just as close with if not closer). When FH said that he didn’t think that was a good idea, his mother suggested/insisted that she (twin sister) take the “Best Man” role… his best friend since forever is the best man and is so excited about it. Let me just say also, that his sisters are completely OK with not being in the BP! This is coming out of nowhere… his sisters had no idea all this was going on. This annoyed me so much because it’s our wedding and our BP and we have it set already and really don’t want to make unneccesary additions AND because she never considered what I may want or what we want). It may not seem like a big deal, but in my mind I can just see how the rest of the planning could go with his mother making “suggestions”.

The only solution I came up with, which FH sisters LOVED, is to have the two of them walk him down the aisle before the BP and myself (all of the groomsmen will be up there already… I’m not a “GM & BM walk down together” kinda gal). Soooo…my question to the brides-to-be and those who are already married is do you plan on having your FH walk down the aisle before you or waiting at the alter (or what did you do if you’re already married)? And, what do you guys think of this idea?

Sorry for the long vent…
