This is the official thread from Hilton HHonors for the Fast Ways to Free Stays (Q2) promotion.

• Members must register for the offer at: www.hhonors.com/freestay
  
• Once registered, stays must begin and end between the offer period. This means that a stay starting April 5 checking out April 10 will not count.
  
• Reward stays, including Q3FN and FN601s will not count towards the offer.
  
• All eligible stays will count for the Q2 promo regardless of booking date, after you register for the promotion.
  
• There is no cap on the rewards. Reward certificates are same as the Q1 offer and can be used at participating hotels worldwide.
  
• Double base points will not count towards tier status. They are counted as bonus points vs. base points. Double points can be earned on reward stays as long as there are incidentals.
  
• Member may participate in any of the airline promos and Q2 promotion simultaneously.
  
• Third party rates do not count towards the offer.
