cocotintin - Are you allowed to choose what type of 45 min band you want?? My cousin who also got married in GWP had 45 min band, but they are an acoustic band, so if you move them into the ballroom, I don't think anyone can hear them.
As for when to open doors, I didn't even think about it. That's for your banquet ops manager to worry. They are the best in judging the situation and deciding when to open the door, so don't over worry.
My bottles for candy bar are from Ikea, but I dressed them up with ribbons and pinwheels. If you want really nice and elegant bottles, you can get them from iwannagohome, but they are V expensive.
I dunno how come extra car park coupons are refundable to the hotel, but we were informed when we bought. There was also another wedding at Tudor ballroom, but even without that wedding, the GWP car park is already quite tight for a single wedding. If you are concerned parking is an issue, you can tell your guests that they can choose to park in York Hotel in Mount Elizabeth. York hotel is also under GWP and they also use Wilson Parking so the parking coupons can be used there.
Missbibi - my coupons are currently pending. I will let you know if the other BTB decide not to take them. I dunno how many guests took my coupons, but prob 25% is a good amount to cater for.
