Dear Hello World,
I mailed 94 separate submissions for the IHG Priceless Surprise game. I sent these entries about 6 weeks ago, but I have not heard anything from you or from IHG.
I understand that this contest has been very popular and that there may be delays in processing. I am just writing to inquire as to the status of my entries.
Here is my information:

Good Afternoon,
Due to the overwhelmingly positive response and participation in the IHG and MasterCard® Priceless Surprises® Promotion, we are resolving a minor delay in delivering Instant Win game plays. Rest assured each and every eligible entry will be fulfilled as we work diligently to distribute any pending Instant Win game plays as soon as possible.
We appreciate the patience of our IHG® Rewards Club members who are participating in this promotion, and thank them for their enthusiasm for Priceless Surprises and their continued loyalty to IHG.
