No way around it, but don't feel bad, because there were no May dates included in the promotion. And no 2009 dates. The dates were limited and so were the resorts & room types available. I got lucky and matched up our April and August dates with the promotion, but didn't get my first choice of resorts. Here are the dates from the promotion flier:
1/6/08-2/2/08; 2/24/08-3/1/08; 3/30/08-4/21/08; 8/10/08-9/27/08
