Peter,
You make an excellent point, and I will certainly consider it. I know I should. I, typically Visa for everything. The US and UA Visa Cards are excellent. I will keep the AMEX in mind, though. I always thought the fees for AMEX were huge, so I never looked into it. I guess that's old school AMEX, not the new variety.
One more question about HYCARD. What if you use a hyatt.com rate with the AMEX and then put cash down for the incidentals? Can you still get HYCARD on a prepaid hyatt.com rate without showing the AMEX at some time? My dad has a HH AMEX, and he said I could use it for the HYCARD promo on hyatt.com rates if I wanted. I know I can't get they AMEX before my next Hyatt stay, so I was just wondering if anyone knew the deal if you book a prepaid rate.
Thanks for the help.
