Not the address IMO
"To enter without completing the minimum two Qualifying Stays,
hand print your full name, complete mailing address, day and evening phone numbers, valid email address, member number, the first six (6) digits of your MasterCard and date of birth on a 3″ x 5″ piece of paper and mail it in an envelope with proper postage to “IHG and MasterCard® Priceless Surprises® Promotion,” c/o HelloWorld, Inc., P.O. Box 5996, Kalamazoo, MI 49003-5996."
Sentence construction dictates that it too must be handwritten. Otherwise, only your name has to be hand printed. Its a bunch of requirements separated by commas and finished off with the word "and".
So many threads should be linked together today.
