Good topic! We are getting married at Las Brisas Huatulco, originally wanted Dreams but it was waay to expensive for family. I have been obsessively watching the prices and since Huatulco is a charter desitanation with Signature being the package provider this year it's been easy to keep an eye on! Lowest price so far has been $698 + $272 tases AI. We leave April 14 and haven't booked yet as prices are still coming down! Chatting with Signature availability on the flights have not been a problem yet for our party of 15.
Have fun planning!
