Exactly this. We had only three park days. Saturday and Sunday were very manageable. Monday in Epcot was insane. Even though I was able to move up FPs and get additional FPs, that afternoon was not fun at all. Between dodging the folks who used strollers as battering rams, getting stuck behind groups who insisted on walking 5 or 6 across and the overall sea of humanity that was the park that day, we were happy to go back to the resort to swim and end the trip on a high note.
