Hi Alan,
Yup for the cards printing, u hv to liaise with the printer. She ll be giving u 2 recommended printers, but up 2 u if u wanna use them..
as for floral arrangement, the last i asked, is that it's pretty standard, unless u want something special, need 2 talk to the florist.
as for actual day banquet, it will be the banquet manager who will assist with the running of the ops..like what Serene mentioned...think it's the same with other hotels too..Hope that helps!
