I think still the best to get ur frens to be MC lah. For me, i'll get my frens to be my MC, one in Chinese, one in English. They're experienced and confirm wun sabo so ok.
I went for many weddings where they get the in-house MC (mostly the restaurant manager) turns out very cheesy. Like my cousin's wedding, the manager actually said that if the champagne cork flies more than 2m then the bride will kiss the groom, if less than 2m, the bride will kiss him instead. Woah.. the groom black face immediately.
