Mandi- About the packages at the GV RM, I guess it depends on how many guests you're having. We anticipated about 80 (but as we get closer it seems more like 60), so our package is a la carte, meaning nothing is included. The WC at the resort are very nice, but of course, they have to stick to the resort's policy and rules...
I actually just back from the GV last night. We went to meet the coordinator, try the foods, and select a venue for our cocktail reception. I was floored by the food tasting, SIMPLY AMAZING! The service is phenomenal too, they make you feel like royalty
We decided to have our cocktail reception by the pool... it was a difficult decision because the resort has so many beautiful options.
About vendors, we hired a separate photographer and DJ. Cost wise, it is the smart thing to do. The resort is charging us 10% of our total cost with our vendor, but it's still much cheaper than using the resort's photographer and DJ, plus all the equipment rental.
In all honesty, I'm really happy we chose this Resort
I hope you find this helpful!
