We had 11 in our group. I split into groups of 2 or 4. Any more than that and nothing came up. If the times I found didn't initially overlap, I selected it anyway and then just played around with times until an overlapping one popped up. Sometimes it took around 10 minutes but it was easy to do in line or on busses. I was never able to get FoP, but was able to get Space, Everest, TSM, R&R, ToT, Peter Pan, and Test Track.
