Just to make sure I looked through my materials from the Royal, this is what it says:
•How late can last the reception at night?
•At the beach until 11PM and the Garden until 10PM. In the ballroom of the Gran Porto until 11PM, in the ballroom of the Royal there is no limit of time.
•If I want to stay longer at my reception dinner is there an extra charge?
•Yes, 10 USD per person per extra hour. It will include the location, service and open bar. If your wedding is in an external area and you would like to have extra hours later than the time allowed, depending on the availability, we could move the group to the ball room.
And, on the reception sheet that you fill out and turn in it says 4 hours. So I supposed you would pay for additional hours. Probably need to check with the WC. But I hope that clears up some confusion. Basically like I previously said, you can be on the beach till 11 but it depends when your reception started...
Personally I'm not going to worry too much about it, I'll just head to a club if the party is still going....
