Hi ¡
Congratulations for your wedding.
I´m a wedding photographer here in Cancun. There are a lot of hotels and places for ceremony. Riu las Americas, Riu Palace, Hyatt, Presidente Hotel.
You can think also in some hotels in Riviera Maya. Iberostar Paraiso, Barcelo, Riu, or Xcaret Park.
Huracan seasson is from September to November so there is a risk of rain but on the other hand you can get better rates on hotels.
If you don´t like the package the hotel offer for wedding, you can make your ceremony in another place.
By the way, in case you need a photografer, visit my site www.cancun-photomemories.com
