I stayed there in 1995. The bus system is AWFUL!!! Rent a car....it is worth it to save the aggravation. I can remember sitting on the floor of the parking lot waiting for the bus to come at 11pm. After being at the parks all day, the last thing I wanted was to wait 30 minutes for a bus, have to stand up, be all cramped with people and then have to visit every single hotel in that area! The drop offs alone took half an hour! We ended up taking cabs everywhere!
I had a little problem with paying, too. The woman who checked us in said I needed to give her a credit card imprint even though I was paying by check at check-in. I asked her if this was going to be charged to my card because, if it was, I would just pay with the charge card and keep the money in my checking account for myself. She assured me that this was just in case I used the phone and then left before paying. So, she took her imprint. I went to use my credit card and they told me that I couldn't make the purcahse because there was a hold on my account! She must have hit some wrong buttons or something! So, there I was in Disney with some of the money in my checking account going to the room (or so I thought) and my credit card funds on hold for 3 days of the vacation.
When I went to check out, I was told I owed the entire balance! To make a long story short, they wouldn't let me leave the hotel and I missed my flight home. Turns out the woman who checked us in locked the check in her safe and left....for vacation. They had to call a locksmith to bust open her safe and get my check out. They called the bank to confirm the money was there and then, finally, I was able to leave. They made flight arrangements and called Tiffany Town Car for me, at their expense.
Moral of the story: pay WAY in advance and rent a car!!
