I'm chatting with a bride right now that got a quote for Now Larimar for dates in Febuary (high season) for land and air including tax for 7 nights $1388 per person (group rate). You should get much less than that since yours is in august!
Let me know if you can work in the 6th room promo...
I'm sooo jealous! ha! Exciting stuff for you... I'm sure your wedding will be great, I can't wait for your review!
