Which place is better DC or Philadelphia

Road trip planning (Washington DC - Philadelphia - New York)

Good evening gentlemen,

I'm currently planning a little "road trip" from Washington DC via Philadelphia to New York.

Currently I have planned a total of 15 days for this, which I have divided up as follows:

- Day 1 - 5 "Washington"

- Day 6 "Six Flags - America"

- Day 7 - 8 "Philadelphia"

- Day 9 "Six Flags - Great Adventure"

- Day 10-15 "New York"

Since I have so far connected a maximum of 2 cities within one vacation by car (or better said by taxi) (Abu Dhabi & Dubai), this is somewhat uncharted territory for me.

Therefore I would like to turn to the experienced travelers who have already made such and even larger road trips themselves to find out whether my planning is "feasible" on site.

I would be happy to receive information, suggestions, improvements and suggestions for adjustments
