That's my wedding group size, too. What resorts are you thinking of?
Lastminbride - You as well? That's amazing! I really want to hear all about the large group DWs. FI and I couldn't handle doing a wedding in town because we would have "had to" invite over 600 people based on our parents. We decided on a small DW with 30-40 of our closest fam and friends instead. I really admire all the couples planning big weddings though, I think the end product will be amazing.
