I just posted a few posts down...thanks everyone for your advice there! Sorry to drag this out...I know this isn't a bad problem to have but I'm not sure how to handle it best...
So I emailed the BM who wanted to have the tea brunch, bc she had emailed me directly asking whether I prefered her idea vs. having it at a BMs house. Here's what I emailed her:
"Thanks for checking-in with me again about this...you guys are all awesome:) I really love both ideas...tea brunch vs. garden party is a pretty impossible decision:) I would hate to feel like you all are having to spend too much money taking everyone out to brunch, so I'm thinking if everyone's ok with [BM]'s place it could be just as perfect! I'm sure whatever you end up doing will be great - I'm just excited to have all of you there...[random non-wedding talk]"
She write me back...
"OK, that’s fine. Just thought it might be easier on everyone planning wise and cheaper. I didn’t feel you needed to know the prices. Some extra thoughts to digest: costs will add up with catering, etc. Not sure if the girls realize this. If they know of ways to get creative that can help a lot! I have some ideas I got from a co-worker who did a tea theme bridal shower too. Let me know what your final decision is."
Now what??? I wish I could just write "talk to them, not me!". (last sentence bolded and underlined by me, not her)
