There are often overlapping promotions with the hotels and airlines. Sometimes the terms and conditions indicate that the promotion is or isn’t combinable with other ones. It is not, however, always clear, whether people writing these terms and conditions actually know what is happening in reality.
Club Carlson currently has the Park Plaza version of their Ultimate Night Giveaway still going on until the August 28th, 2012. Then there is the bonus promotion of 10000 bonus points for stays of two nights or longer in the Asia Pacific region.
The terms of the latter promotion includes the following exclusion:
This Promotion may not be used in conjunction with any other package, promotion, discounts or bonus points programmes. Participating Hotels are subject to change without notice.
This is fairly typical copy paste that these chains tend to have on each of their promotions. Based on this and what you might hear if calling the customer service, you may come to conclusion that these two promotions are not combinable.

Points posted for the both promotions exactly as I expected.
It always makes sense to sign up for all possible promotions.
Terms and conditions often include words that the promotion cannot be combine with other ones, but that is often not the case. Contacting customer service in advance of your stay to seek clarification is often fruitless as they go by the written rules of the promo.
