Hi Kristine,
Not to worry, I had my tea ceremony at Fullerton,b4 the lunch too. They will give you a function room for the tea ceremony, big enough for abt 30 pax, with some simple decorations,the function room is on the same floor and near the main ballroom..and their staffs will help you with the pouring of tea also.Tea is provided by Jade..Worries free..hee.
They also gave me a day room for helpers. All these are not stated in my contract.
If you are worried, can always voice your concerns to your coordinator..=)
