DHalltheway, Thank you for your suggestion.
After some hours of reading and reading, I have came to a conclusion myself.
First, on stays with status with Hyatt compared to stays without status with SPG.
I have decided to give my business to Hyatt due to the status being given to me during my challenge.
I see the 4 suite upgrade certs, breakfast, lounge and upgrades that outweigh the challenge set forth by SPG.
I have read at
http://travel.bart.la/2011/04/12/hya...tch-challenge/ that I will receive another 4 suite upgrade certs after retaining Diamond after the challenge. So gonna stay at Hyatt when I bring my parents to HK during Chinese New Year next year.
Is this right?
Secondly,
For a place I travel to that does not have a Hyatt but has a SPG, there's still IHG for me to choose. So not much of big losses here.
Thirdly,
The differences in prices of hyatt and SPG in places that I am going are not substantial and in fact, the Grand Hyatt Beijing is cheaper than Westin or St Regis.
I am hoping that I am making the right choice here. thanks to FT for helping me embark a new journey with Hyatt.
