Been asking myself that same question for about 7 years. I like to pay my hotel reservations off (as many do) in advance. Many people will say "It's Loews", and that's all well and good, but Universal needs to make the process easier. Just in case you didn't know, here's what needs to be done:
1.Fill the form out.
2.Make photocopy of your drivers license.
3.Make photocopy of front of credit card and back.
4.Fax all 3 forms out to number on form.
Now, let's say an AP rate comes out at Portofino but you're booked at Royal Pacific and you want to switch, you would need to contact Loews accounting department, cancel the reservation, and wait for the refund. Then, you'd have to rebook the new reservation with a 1 night deposit on your credit card, and if you want to pay it off, go through the entire process above all over again.
No doubt, this is one area where Disney has Universal beat hands down.
