Crockfords and Highlands executive suite needs roughly 1k TP/day, Highlands roughly 150-250TP/day. Not sure about requirement for Genting Grand Club suite.
Don't need 1k bah. The last trip I went the highest tp I earn 1 day is 400tp. Also got highland executive suite and genting grand club suite. I think is total tier point earn per year bah. As long as yearly can earn 1k plus tp above or 2k tp per year, can see all the good free room already. But then use to be able to use apps book 6 nights straight, now limited to nights max. Don't know is it need to call in to get longer stay or my free nights limited already.
