Doubting my plan for. MNSSHP day

Any tips on where to watch Hallowishes from if we plan to go directly to Frontierland after for the second parade?

I agree about second floor of train station. It is also a great spot for the parades. My son and I were there over Spring Break. Many of the characters are on top of the floats in the parade. From the second floor, you are eye level with them. Only a few chairs, so get there early if that’s important.
