We probably FP about 3 times each day. If the line is less than 20 minutes, then we wait or get a FP and get in line. Then we can usually ride again when we get out. If the FP return time isn't until later in the day, then we just don't bother. We mostly use FP early in the day. Say....Epcot..we get a FP for TT and then go over to M:S. Usually we have about a 10 min. wait until FP time, so we have a bathroom break. If we are in the area of another FP attraction when our window opens up, then we send dh over to get new FPs and then ride the current FP attraction. Although, I have been seeing more CM abuse of FPs. When we were there in Dec there was a CM at SM who had a handful of FPs. There was a group of about 4-5 teen-age girls in front of us. The CM gave all of them FPs!! Saw that about 3 or 4 times. What's up with that practice??
