Me too - that's what I was asking about as well.
I get what Bluer101

was saying that pre-payment is not a requirement, but when our family travels we always pay for our hotel, tickets and excursions before we even arrive. I would love any info on how to make it happen online. If not, I'll call as Damo originally stated. What I DON'T want to happen is that I don't get some sort of receipt showing that the payment has been made and there are problems with the hotel upon arrival.
