Hi there!! Congrats on your engagement. You have definitely come to the right place to plan your destination wedding -- this site is a gold mine for ideas and tips for destination couples. I was a destination bride myself 10 years ago and lived on this site obsessively for 2 years
For the Dominican Republic, I think a great resort that fits what you're looking for is Now Onyx! They have amazing swimup suites, they are an oceanfront resort and best of all, they have both an incredible adults only section with the best pool area and a family friendly areas as well. The adults in your group will also have access to Breathless Punta Cana, which is next door where they have a great nightclub and casino but they can also use all the amenities there as well (as long as the property has not been bought out for your travel dates).
I along with a few agents of Wright Travel Agency, which is the official agency of this forum, stayed there for 4 days this past January and I was thoroughly impressed with the accommodations, amenities, food and excellent service. Also, they have an amazing wedding team there that does everything to please couples and give them the wedding of their dreams!
If you want information about this resort and pricing, I suggest you contact Wright Travel Agency and one of their Dominican Republic specialist will get back to you! Wright Travel also has exclusive promos and discounts to many resorts -- including this one. There is a great promo called the Bride and Groom Fly Free credit, which can save you up to $1,000!!! You can contact them here www.wrighttravelagency.com or email directly at firstname.lastname@example.org
Hope that helps and again, congrats!!! ❤️
