I ended mine at 10.30pm. =)
I think you really need good helpers and remind your guests to come early, tell them because is a Sunday n need to end banquet early as Monday is a work day.
I printed in my card half an hour earlier den normal. 6pm for reception n 6.30pm for dinner (normal is 6.30pm recept n 7pm dinner). Although mostly come at 7pm+. But is good to tell your guest b4 your wedding. I always told them "don't have to come early, just come on time will do".
Because nowadays ppl just listen in n listen out when u tell them to come early, this has become useless. So tell them something different will make them remember. =)
And if you wana end fast, you need a really good Makeup Artist. Mine was fast, and my friend went up with me to help me change, she also help my MUA to hold the perm iron while she does my makeup den go back to roll the perms den my friend will help to hold n she conti to do makeup on n on... Really good multi tasking.
I have 3 hair do. One hair do is at reception to greet guest. den 20mins b4 first march-in, i went up to change to another hairstyle and put on mask as wedding was masquarade. Before i went up, i notice that the crowd was alot already, so when I'm up for like 10mins, I requested my helpers to have the ballroom door open and have guests seated. den 10 mins later, i went down, everyone was inside. Just nice.
I went up to do my 2nd march-in like 5mins after first dish is served (normaly was on 2nd dish but i went up early). So i think all add up to make it possible to end early.
One more tips, i have alot of things going on at the reception, free gifts and photobooth with lots of mask for them to take picture with, so as to keep them busy, so ppl won't leave the place (eg.smoking) n during ballroom door open or during march-in den your guests start returning back. Not so nice. So something at the reception to keep them there is good.
btw, yap they don't have 20 pax table, only a few hotels in Spore have that. But i don't think GPCH will have as it takes up too much space.
