For those who used the Freedom offer, did the store still have the AMEX surcharge? (IIRC when I last shopped there earlier this year, there was no charge for Visa/MC and a 1.9% fee or thereabouts for AMEX and Diners.)
Also, made use of the latest Hilton offer this week at HSW. No issue splitting payment across two cards at the front desk for $300 back on a $600 stay. Very happy - very likely would have booked elsewhere otherwise.
No surcharge at all.
