Do this now: Club Carlson first quarter promotion
/Between January 6 and April 13, 2014, you can earn 38,000 Club Carlson Gold Points after completing 3 paid (not Points + Cash) nights at any Club Carlson properties worldwide. You can only earn the bonus once.
While this is a lucrative promotion (as Frequent Miler shows here), I strongly doubt I'll participate, since I can manufacture 53,000 Club Carlson points for $83 (by buying 21 Vanilla Reload Network reload cards), rather than the $180 Frequent Miler moots in his post. But if you have some upcoming paid Club Carlson stays anyway, this is a very generous bonus.
