We picked DW for many of the same reasons. This is also Maurice's second wedding so we also thought that a DW would include those that really wanted to share in "our" day. Plus, now here comes the selfish diva in me, I couldn't imagine just one day of celebration.
Hell, let's have an entire weekend!!!!!
Similar to Sarah, FI's mother is pretty highly regarded so that meant even more people to pay for. While we've avoided that slightly DW just seemed like the thing to do and would set our day apart.
