    "A big thanks to Joan and team at 1-Altitude Coast for the wonderful wedding experience! The wedding turned out to be everything we hoped for, absolutely recommended!"

    LIANG JIE T.

    "We had a great experience hosting our wedding at 1-Altitude Coast. Loved the innovative idea of having a mock wedding so we can experience how our guests might experience our wedding. The food was great and there was also a complimentary wine and live station tasting. One of the determining factors that drew us to the venue is the option of having a water stage which we absolutely loved although we did have a lot of anxiety because it is subjected to weather conditions. But overall the venue and ambience was great and we felt that it was almost the perfect wedding that we were envisioning. Of course, it was possible thanks to Joan and her team who were with us throughout the journey. Joan herself also stayed late into the night of the wedding to help us out. Much thanks again to helping us create such a dreamy wedding!"
