I'm mostly use Wyndham hotels which is la Quinta comfort inn, staybridge, I think and a couple like that kind of medium budget hotels. I try and stay at those because of the points also use a credit card that accrues points just for those hotels.
I do like courtyard but that's a Marriott and I rarely stay there but I do collect points. I like la Quinta the best because they have a decent free breakfast and pretty nice rooms most of the time.
