Yes! I've spoken to Laura in extreme detail! She's been good answering everything. You will have to pick a wedding package - there's three tiers to chose from. We're going with the DREAM tier with has the most options - like mani/pedi, bouquets, musician at the cocktail hour etc. It's pretty cool.
The reception can be done in various restaurants. (Grazie, Steak House, Meditterean restaurant) A totally private reception is available too BUT you will have to pay for the food. It's an average of $110/person for buffet and $85/person for a 3 course meal. So on top of your wedding package price which is around $2000 you will have to pay for everyones dinner too at the private reception. So for 40 people, the sit down dinner will be $3400 on top of your already $2000 wedding package! So be careful of the hidden costs.
Centrepieces are averging around $180/ea. The most expensive ones I saw were $400.
If you want the resorts photographer its free to have him onsite but if you have another photographer in Punta Cana there is a $450 vendor fee to have him just on the premise!
I've only really discussed flowers as decoration so far but anything is possible just expect a pretty hefty cost!
Hope that helps!
