While we wish the key to what a credit card does is the email or terms the biggest key to what a credit card does is what your limit is, how much you spend per year and how often you charge back (virtually never for me). If they are making 2.5% or whatever of $500k in charges per year or whatever no way in hell are they not reversing any $1000 charge even if they side with the hotel- they would likely eat it.
