Robo, I booked two second tier FP+ that I'm not really interested in doing and one tier 1 pass that I'm wanting to do. I actually don't think we'll show up at the park until time to ride the last tier one attraction. We probably won't arrive early enough to use my tier two attraction FP+. If we arrive and just use the last of the three reserved FP+ ....at the end of that last attraction may I then try booking another tier 1 attraction FP+...even if we never used the first two FP+s that expired?
