hey! i had to pitch in here.... hee hee hee this is sounding awfully familiar....
so my hubby and i married when we were 40 - we had a whole lot of 'been there done that' with the whole wedding thing. so we decided we'd do it the way WE wanted to - cheap (for lots of reasons), easy, and fun.
my soon to be MIL totally blew a gasket over everything - including get this - when we told everyone that we would prefer that 'no one' stayed at the house with us .... she thought it meant everyone but HER. she couldnt understand why we wanted to be alone on our wedding nite!
so we told her if she didnt like it she could visit us the next weekend.
she got the message and a hotel room.
we had the best wedding ever - at the farm, 'rustic' (cheap), we had BBQ and got married under the crabapple tree with all our nieces and nephews standing around us. we had cupcakes for the cake and everyone was outside. our invites said to wear comfortable shoes and 'the bride isnt wearing a dress so you dont have to either.'
since we were older most of the folks there had seen lots of weddings and we got rave reviews.
if the whole big puffy dress with 700 of your not so closest friends doesnt agree with you - do it your own way. i guarantee you you will only regret being pushed into something you dont want - or worse be saddled with a huge bill. plan on having a big blow our for your 10th anniversary and remind any naysayers that this is the start of YOUR OWN LIVES TOGETHER.
good luck!
ps at this point i wouldnt take any $$ from her if she offered. sounds like it would come with strings. there are plenty of sites out there on 'how to' save $$. PM me if you need ideas.
