This is kinda last minute but,

If you guys are looking for a more scenic drive than all highway, take this:
290 -> 395 to CT
get off at Route 44 in Putnam CT, head east to Rt 102 in Glocester RI
then take Rt 102 all the way into Kingston/Newport.
(From there take 1A to 138 which will get you over the bridge to Newport.)

We go this way all the time when we visit our family in N. Kingstown, it's only about a 10 minute difference from my house (if you drive the speed limit on the highway) and so much more peaceful than driving all highway.

I'm definitely not going. See my post in Common Interests.
