I've had hoppers before and never used them. This trip, I think I'm going to add them though, because we don't know what we're doing on our last park day. I envision that we'll get a FOP fast pass on that last day, but likely won't want to stay in that park all day. Then, because we would have the hoppers, we may do the evening hours at other parks than our planned park day. There is also one day during our trip that has conflicting crowd ratings on different sites. So that day we may end up leaving our planned park if it gets to crowded. For us, it's really more like an insurance policy.
