Wedding on Ecstasy

[Maggie]

I posted this on the Carnival board then decided maybe this was the best place for advice. My son and his fiancee' are going on a cruise to Cozumel where they are going to get married. They wanted to have a reception for their guests but have found the prices out of their price range. They only have the beach site for 1 hour and the band would be 375.00 alone. I have called Carnival and found out they can book a cocktail party/reception on board but that can only be done one of the days at sea. I was thinking they could go back on board and go to one of the lounges and have a small celebration there. Does anyone have any recomendations or knowledge if we can do this without getting into trouble with Carnival?

Thanks to any and all that respond.
