If anyone has any advice for routes, lodging or pitfalls to avoid . . . I'm thinking about going DC area (MD suburbs) to NYC next month via York PA. "Credit card" trip with minimal luggage.

Day 1+2 to York PA via Torrey Brown/York Cnty Heritage Trail - with overnight stop where? (Alt. - do it all on Day 1 and take Day 2 as a rest day).
Day 3 toward Valley Forge area
Day 4 to eastern Bucks County or Princeton area via Schuylkill
Day 5 to NYC

Especially interested in days 1-3. Found a few routes for day 4. Have ridden day 5 several times. Thanks for reading!

Edit: thought I was posting in Touring. Hope this is ok.
