I would really be tempted to give no reason! Just say no really, do they have RSVP cards? That may make it easier.
Just "I'm really sorry, but we aren't able to make your wedding, i hope the weather treats you well, and your lovely day is all you envisaged.
I look forward to seeing photos you as a beautiful bride alongside your new husband

Love

Xxx"

Something along those lines where you make a whole paragraph, then people wont even realize why you said no. If they prod further, then think about reasons lol.
