Did my first of two stays yesterday and have a really cheap HI booked for next Sunday to complete my tasks. Cost me around £110 for 2 nights i needed and earn nearly 19000 points. They'll go towards some overpriced Boston, San Francisco or New York stay.
The double points one I'm not going to go out of my way for, but if I'm staying in IHG hotels, 500+ extra points here and there all add up on top of 200 points welcome bonuses etc.
