Careful with the MegaBonus offer. I believe it is worded for each 2 paid stays gets a free night. If it is 6 consecutive weeks without checking out they will probably consider that 1 stay. There is another thread in this section for the Gold Challenge thru HSBC China or something. I do not have an HSBC card, nor live in China, but signed up and gave me the gold challenge. Stay 8 nights in 90 days and get Gold status. Also, gives you status a few days after you sign up, nights just needed to maintain it.
