Adri2013

I was hoping someone might be able to provide with some guidance/suggestions... My fiancée and I will be getting married at Dreams Riviera Cancun in April 2013. The wedding itself is booked and we've had great service from our wedding coordinator. We are expecting a fairly large number of guests (between 30 and 50 guests). My concern is around group bookings. We are hoping to secure some sort of group discount for our guests. We have contacted the group booking people four times (3 voicemail messages and 1 email) and they have not gotten back to us at all. Does anyone have any suggestions or ideas on who we should be contacting or how we should go about this? Are we doing something wrong? I've got to say that I'm disappointed that the resort isn't being helpful about this. We are potentially bringing a large amount of business their way. Thanks!!!!
