ok, so that offer posted we weren't eligible for but they do have other promotion ongoing which is what was offered and requires the attendance at the presentation.
Will have a think about it, but the offer was $299USD for dates in Jan if anyone is interested, there was a Festival surcharge below for specific dates: USD 200/night
Dec 21-Jan 7, Feb 9-15 Lunar CNY, April Easter holiday, May 1-5, Oct 1-7
