If you are coming from the East Coast, a Sunday morning rope drop at DL is not that early of a morning. Everyone seems to have a slightly different definition of “rope drop”. For me, rope dropping means I’m standing at the rope and when it drops, I’m briskly walking to Peter Pan, Space Mountain or perhaps RotR. If you are truly rope dropping and are at or near the rope drop area for Fantasyland, you would have absolutely no problem riding 2 rides in FL and making your 8:10 reservation at Plaza Inn (The Pp AiWL combo might be a stretch but almost any other FL combo can typically be accomplished in 10 min at a true rope drop. In fact, it might even be slightly easier to double back to Plaza Inn if you wait until 8:10 am to do so as there will likely be fewer guests heading into FL from Main Street. Now, if your definition of rope drop is simply scanning into DL prior to 8:00 am and sauntering down Main Street to join the rope drop crowd on the outskirts of the hub, then you may not have time to ride an attraction in FL prior to your Plaza Inn reservation.
