Anyone know if New York-New Orleans (stopping off along the way) is practical in a 2-3 week period?
And if so which route or mode of transport would work best?
Used to drive over the road .. that's a 1 day run, non-stop. I'd take I-95 down the eastern seaboard (see some cool sights- Washington, Philly, N & S Carolina) then cut across from Jacksonville, FL, or Orlando (Disney World?) on I-10 to NO.
OR, cut across to I-81 & down through VA, TN, (Mountains) then I-40 across through Nashville to Memphis, and I-55 down to NO.
Either way, you'll see some great sights. If you wanted you could round trip it ... down one way and back up the other very easily. Figure on 4-5 days driving 4-5 hours for each leg. I'd do convertible if in the summer .. ride w/ A/C or Air, whichever you like.
If you really wanted to branch out, in that amount of time you could easily swing by Chicago and down, or even go clear to Cali with little to no effort driving wise.
Advice for any road trip in US - book hotel/motel w/ a pool !! Nice to stretch/ease after driving so much.
