what to do with 10,000 miles....

I have 10,000 miles & a trip to North East of the USA booked.
Wondering what I can do with them..
I am guessing transferring them to a hotel partner - unless I can somehow use them for Car Rental?
I have already sorted out rooms for 2 legs of my trip, but still have to sort out a stop over in Hershey or Lancaster. Washington DC, Philly & New York.
I am quite happy with a no frills room as TBH I dont plan on spending much more than sleeping time there.
What would be the best partner to transfer them to? I am assuming by the time I need to use them, I will have a lot more than 10,000 miles, but nowhere near enough to bother keeping for another trip....
