I've moved a lot of stays to Hilton. The free breakfast as a gold is something that was always missing at IHG and the rooms are fairly equal in price to HIs in Europe. I've already gotten enough points in the last 4 months for a free week in the Maldives.
I've now rented apartments in my main focus cities in China so that I don't have to even stay at hotels. It's definitely a cutback in terms of earnings, but I have a suite every night. It's amazing what you can get in China for the price of a 5 night IC stay.....
2-for-1 and 35% off are still useful for me for airport stays and such.
