You may want to get on the forum and find someone to share a rental car. A cab from the airport may be expensive, but you can always take the subway ("the T") to Braintree... and get a cab from there... much cheaper.

Note: The Hotels (Comfort Inn, Radisson, and Best Western) are on Hingham Rd just off of Route 3 (exit 14). By taking route 3 North toward Boston, numbers go up (exit 15, 16, 17) and by going South toward Cape Cod, exits go down (13, 12, 11).

Exit 14: Hotels, Home Depot, and some small shops and restaurants
Exit 15: Derby Street Shoppes (rehearsal luncheon here)
Exit 17: Shopping Center, BedBath&Beyond, Braintree Subway Station

* Take Left out of Comfort Inn or Right out of Radisson/Best Western.
* Continue roughly 1/2 mile until the Rte 3 bridge.
* Take Route 3 South.
* Take exit 13, Hanover Mall/Norwell/Scituate.

* Take a right at the sign and follow it straight for about 2 miles.
* You will come to another sign on your left for The River Club.
* Take that left onto Border Street.
* The River Club is 1/4 mile on Right, 78 Border Street.
