You can't call the resort itself unless you're onsite using a house phone. You can only call the resort call center at 407-934-8000. If they provided an 800 number direct to the resort, can you imagine how many calls they would get? They would never have time to take care of the guests!
I know but thought maybe one existed. I just called the hotel direct anyway and said I had a question on a bill and they transferred me to a main call billing center anyway. That was actually the number I wanted. The actual name of the department is Resort Research and Billing.
