Hi Maria! Welcome! I'm a newbie too.
I'm also planning on getting married at Moon Palace. We're already booked for MP Cancun, but would really like to get married at MP in Punta Cana - mostly because we've heard the beaches are A LOT better there. I've been on several family vacations in MP Cancun and haven't been very satisfied with the beaches.
We talked to our wedding planner about changing the location - she said they will know in January if/when they will start performing weddings (our wedding date is June 12, 2009). They may not be ready in time for our wedding, but I see yours is in November 09 - they should definitly be ready by then!
Happy Planning!
