The way I would recommend is to take
Take RT 95 North through Providence and into Massachusetts up to Route 495 South towards Cape Cod
The rest below I pulled off Google Maps:
Take the I-495 S exit 6A to Cape Cod - go 21 mi
Take the RT-105 exit 4 to Middleboro Ctr./Lakeville - go 0.2 mi
Bear left onto the RT-105 N ramp to Middleboro Ctr. - go 215 ft
Turn left at S Main St - go 0.4 mi
Turn left at W Grove St - go 0.2 mi
Turn right at Elm St - go 0.1 mi
Here is the link to the map - if click on "A", the Mitchell Club, you can ask for directions to there from New London, CT as well - probably the same.
