Nikiko,
shld b ok for the timing like tat. u can get out after 2nd dish then go bk ard 4th to 5th dish. depends on hw many tables u hv lar.
but dun tink need 20-25mins ba. u c when PS, mua change 1 hairstyle n plus touch up also nt tat long. so i tink no prob if u wan to hv her stay for the 2nd march in.
u can request the mua to go dwn to the dinner area for a drink or wat lor. becoz very fast after u march in, u have to go change liao.
Jo,
u can put ur ang pows in the safe. becoz if ur brother wan to bring it ard, it will b difficult for him also. actually also nt safe...
