hi scyy!
i've been to my friend's wedding in Copthorne King's Hotel and there were about 70 of us who attended their wedding. i know Copthorne can cater to weddings with a min capacity of 6 tables on weekdays. Hotel Re! and Pan Pacific Orchard are also great venues for smaller weddings.
rates are more expensive for weekend weddings. so if you want to cut down your expenses, i suggest you have your wedding on a weekday. you can save as much as $100.
