You can only see the top parts of the parade so I imagine a four year old would have problems seeing the parade. We were four adults and were able to enjoy the parade. Being able to relax and not be crowded was worth the sacrifice of not being up close for the parade.September will be our first trip to WDW. We have FP+ for MSEP and Wishes one evening. Can we watch MSEP from the Wishes viewing area? Our daughter will be almost 4 if that matters for the view.
We're not too concerned about "wasting" our FP, as we have A&E at 7pm that evening and were planning to RD, go back to POR around noon and then not come back until after dinner. But if we could use that other FP for something else, then we would.
