I mainly open the these hotel cards for sign on bonus. Unless your fess is low, like IHG grandfather $49, it may be hard to justify to keep all majors hotel brand credit card from overhead perspective( Marriott, IHG, Hilton, Hyatt). You would rather focus on one or two and multiple free night award. In most cases, one free night award probably doesn't do any good as you may need multiple nights for a stay.
