Hotel credit card for cross-America road trip.
I am planning a 1-2 month trip from coast to coast in late summer or early fall of 2016. I am hoping to rack up some miles, both through introductory bonuses and from general spending, before that time so I can get perhaps a week or two of hotel nights for free.
I have an airline credit card (Southwest) and several general points cards (AmEx, Chase Freedom, Citi Forward) but no hotel cards, nor do I have experience with them or know much about them. Are there clear winners for points value/points building efficiency?
I don't really have a preference for any given chain. I tend to stay in Best Westerns, Holiday Inns, or Hampton Inns when traveling fwiw.
Any advice or guidance would be greatly appreciated!
