We did PhotoPass last time, and don't think we'll do MM this time. It's only two of us, and as another person said, there are only so many ways to pose with a small group! And the photographers are very willing to use your camera/phone.
Another thing I'd add is that last trip, we were trying to get a selfie (before the days of selfie sticks--don't worry, we wouldn't do that to you all! LOL!) and a couple came over and said they'd take one of us if we'd take one of them. Agreed! After that, it was like a light went on. We saw couples, we said we'd take their photo if they'd do ours. Then we asked families where the mom/dad was trying to take a photo--hey, get in the pic with your family, then take one of us! We found every person we approached was glad to do so, in fact, very happy about it. We totally plan on doing that this time.
