As you exit from Logan Airport, you want to turn left (South) on and go through the Sumner Tunnel ($1 toll). Do not attempt to use the Ted William's tunnel, which is only open to commercial traffic.

If traffic is light:
The electric sign will direct you to turn left (South) on directly towards the Sumner Tunnel.

If traffic is heavy:
The electric sign and state police will require you to take the "alternate route" to Sumner Tunnel:

Turn right (North) on , away from the tunnel. Get off at the first exit and keep to the left down the exit ramp. At the bottom of the ramp make a U-turn back onto , heading South towards the tunnel.

Try to develop a sense of patience. This really is not as difficult as it sounds. You'll be in line with a few hundred taxis. Just follow them around the loop.

You should be in the left lane going into and through the Sumner tunnel. Upon exiting the Sumner Tunnel, make a broad right and go up the highway entrance ramp (which leads to north). Take North all the way to New Hampshire's Exit .

From Exit turn right onto Candia Road. At the first traffic light turn right onto East Industrial Park. Approximately 3/4 a mile turn left onto Holt Ave. We are the second Building on the left (900 Holt Avenue).
 

Once in New Hampshire, bare left onto and West , after you cross the bridge over the Merrimack river (approx. 1-1/2 miles) turn north on . Take exit 5 and turn right onto Granite Street. Turn left onto Elm Street. The Holiday Inn Plaza is on the left (700 Elm Street, 603-625-1000).
