Where do you need to be in SZ? Bigger city than you night think. If in Futian by the Mrt, or the convention center, then I would recommend the Ritz Carlton or the Shangri-La. ritz is smaller, better service, but Shangri-La has more facilities, restaurant options. Ritz is closer to convention center. definitely spring for club floor in either one, gives so much value in free breakfast and meeting rooms.

Good luck!
