I read about here on the DIS before I left or wouldn't have known about it. The day I booked it was a pain. I took the bus early that morning from CBR to DTD only to find the boats weren't running yet, so I had to go back and catch a bus to POFQ. I had called CRO who said they couldn't help me, but to go to PO. I asked POFQ or PORS and was told either one. When I arrived at POFQ guest services knew nothing about it, but called and verified it could be booked at PORS, so I got on another bus and went to PORS only to find the kiosk didn't open until 1:00pm. Once the guy finally arrived he was very nice and talkative telling me and another couple that the Bounce Back was much more popular than Disney anticipated and they were shocked at how many people knew about it despite deliberately not promoting it very much. (No duh!) I wasted an entire morning trying to book it.
