Yes, great idea, hope you enjoy.
Here are some options:
Just like the weather, it's hard to predict when peak color will occur. It may or may not coincide with your time here.
When are you planning this? As springerandy suggested, planning this trip for a given time frame may not pan out. I planned a tulip festival trip to Ottawa once & half the tulips sere gone. I also took a trip to New Hampshire which was advertised as a fall foliage trip & the leaves started turning on the way back hoem.
This is another cruise to look into: https://seastreak.com/daytrips-and-getaways/fall-foliage-cruises/
This website has a Fall Report that gets updated each week showing where colours are just starting or at their peak or past peak. Upstate New York starts first then works south.
It hasn't been updated since last November for obvious reasons, but should start to be updated again sometime in October.
The big problem is selecting the right date. Generally, the leaves change sooner up the river. The "heat reservoir" of Manhattan is not conducive to the best color. Rain and temperatures all figure into the equation.
