Hello Dawn,
I love Copal and i actually thought about having my wedding there but my family was not really happy with the idea because the "cabañas" concept is not for everyone.
Everytime i go to tulum i like to stay in copal but you can have your ceremony there and offer other resorts in tulum where your guests can stay, if they like the AI there are several a few minutes from there or other cabañas that are more "comfortable"...
However i think it is a great idea and a great place but you have to think in others...
If you need ideas, let me know!!
Yazmin.
