By MBS do you mean the convention halls? If so, I attended weddings there twice. Firstly, it's a very very far walk from the carpark. Heard the elderly complain about it too. Secondly, food is so-so, no impression of it at all. Thirdly, yes! Many rooms, many weddings happening at the same time. During 1 of them, I stepped out to go to the restroom & I saw more than a couple of brides waiting outisde their respective function room for their march-in. Quite funny.
