BM shopping (this is long)

Okay a little background I didn't get to go dress shopping with my mom. so I want her to come BM shopping with us because she hasn't been apart of any of the wedding planning, she doesn't have a car. My MOH is my 16 yr old sister and one of my BMs family lives in the same town but she lives upstate she visits them often. I live an hour away from the town and would take the train. The other BM lives 15 minuets from the same town so i though the town would be the best to go BM shopping. But I cant seem to get everyone together... four months until the wedding. we can only do weekends and every weekend this month someone has something to do. They all have different budgets and taste I want them to be happy with the dress and price what should I do?

Go with each of them separately that is going to cost 100 in train tickets and three weeks and then pick a common dress and have them order it (by the time this is done will there be enough time for them to come in and be altered?)

There is a day that only one girl would be missing but I feel terrible leaving them out then she would have to go there alone.

Go with my mom pick out three I think they might like and let them go on their own time and look at them and tell me (I also feel bad about this because I would like to see them)

or wait until October and see if that is a better time for everyone and hope there is enough time.

any advice??

i know that that will really hurt her feelings and the reason she cant be there is a family matter


ETA: but your probably right

I'm not bringing all my bm's shopping. I'm bringing 2, picking the dress, and that's what they're wearing. I may sound like a bridezilla, but I'm not getting involved with 8 opinions, I feel like no decision would ever be made.

I'm sure you've done research online, show the girls the dresses and get a vibe from them that way. Have a few of them try on the top contenders, that may make your life easier. You want your girls to look great, but it's also your wedding, and they should be wearing what you envision for them.
