Your detailed directions were great. I opened up my road atlas and went through each one in great detail. Thank you. It looks like #2 is the most direct route. It does involve staying on 95 for all of CT which I know can get backed up. I'm leaving on a Thursday morning and returning on a Monday so to avoid horrific Friday and Sunday traffic.
Assuming traffic flows, how long is the drive from Providence to Hyannis going as you specified in #2? In particular, how long does it take?
