Weddingbee boards

We currently in the process of sending out invitations for our wedding and the parents of my bride to be are insisting that we do not invite a few particular individuals (we are only inviting them to the evening!).  They are friends of the bride rather than myself but I have met them and am more than happy to invite them.

The individuals in question are not criminals or anything like that and her parents don't think this either, they are just of the opinion that these people aren't 'close enough friends' and we shouldn't be inviting them.

I should mention that the brides parents are paying for the reception and some other bits and bobs with us paying the rest.  Given that I am happy for the brides parents to have an input on how many people we invite but don't think it is fair that they can decide who in particualr we can or cannot invite.  They have already said that this isn't about how many people are invited and as such I think its not on that they try and veto guests we want to invite, especially as we have told them that they are free to invite their own friends and work colleagues to the evening if they want to.

Of course its pretty tough for me to bring this up with my in-laws to be and I don't want to start a big argument but I just want some opinion on whether I'm right to think that they are being unreasonable?
