Just returned from Hong Kong
Disneyland. After spending more time in the parks (on 3 different days), I have a little more information on PhotoPass than my first report.
I looked back at the brochures they are handing out in the Disneyland Hotel and at the park and they really don't accurately describe the current product. They say "Get your 'Disney Photopass' Card from any Photographer. Save the photos, view, and purchase them at photo sales locations."
As I mentioned in my last report, the photographers aren't using the scannable cards and are instead handing out paper slips. You only get the card when you buy all your photos at the end of the day from the photo sales locations. But perhaps the fact that they are advertising this way means the HKDL intends to move to the system we know and love where the photogs can add photos to your card with the scan of a barcode. That would certainly be easier!
We did purchase Photopass on our longest day in the park, at 398 HKD. We just made sure to see as many characters as we could that day, and stop for photos when we saw the photographers. Problem was -- there aren't enough photographers in the park! You can reliably find them in front of the castle, and at all the meet and greet locations in Fantasy Gardens. We also saw them in front of Mystic Manor, and at one of the two princess meet and greet locations to the right and front of the castle. But disappointingly, there were no photographers in front of the Disneyland Railroad Station when you enter the park where everyone wants to get a photo. And we didn't see them at the Chip & Dale meet and greet in Grizzly Gulch. And I didn't see them roaming anywhere else either.
Overall, I felt I got my money's worth (got between 40-50 photos in 4 different locations), but the system needs some improvement for sure!
