in a german magazine i've read a post about getting a suite upgrade or upgrade to club rooms for just a few bucks. -- but in order to know how it's going to work i would have to buy a membership to this magazine...

i'm going to travel in south korea for two weeks and since the hotels are quite expensive i'm interested in ways to lower the prices i have to pay for hotels there.

any ideas how to pay less for club rooms at the hyatt?

thanks!
