Not sure about the wedding banquet package but we're actually having a ticketed event held at MBS soon. And there's alot of dissent going on because of their charges. Apparently, they are charging for the ballrooms, electricity and some other stuff separately from the menu itself. Which are usually included for other hotels. Free flow soft drinks are also usually included in other hotels but it's charged separately apparently. I don't know if it's only done to like unsuspecting individuals or what because based on my research that is not the industry standard.
But well, if you have deep pockets and is keen on trying something new and your motto is "spare no costs" i suppose you could try and share your experience.
