The one hotel I love to stay with and probably blog too much about is IHG. I just love PointBreaks nights for 5000 points with 10% back when you have their Chase branded card.
Right now there is this promo going on that can get you $75 cash back for two stays.
Note you need to be logged in to your Priority Club account to see the above and register. You can also read all the T&C about the promo HERE. And once you have registered and stayed you submit your info for the rebate HERE. And last but not least there is a 1000 point bonus per stay from FB HERE. There are many codes you should try before you stay at an IHG hotel and they are all listed at Flyer Talk HERE.
Also, the current PointBreaks list is about to end on May 31st. Normally they come out with the new one any time from the 15th of the month proceeding the end date up to the last day of the old promo. All the blogs will post about it when it happens but it is good to be proactive and be ready as there can be big bonus points for booking right away as well as getting the nights for the hotels you want in June and July! – Rene
